Doing it Right...the First Time!
So you want to shave the handles off your car or truck to give it
that smooth, uncluttered look. Great! But do you know everything
that you need to know so that you will get the right parts and the job
will come out the way you want it?
This booklet on Entry Systems was designed to give you the
information that you need on each part of a complete entry system so that
you can make the right choices and get the right parts... the first time!
Questions You Need to Ask
To start designing your system consider the following - How do you
want your system to operate? There are a variety of "actuators" and ways
to trigger them. What type of switches fit your needs? Are you keeping
your original latches? Are they in good working condition?
The answers to these questions will lead you to make selections in 4
separate sub-systems: the Safety System (locking and back-up
entry), the Triggering System (the switches or remote control), the
Power System (what actually releases the latches), and the
Latches themselves.
Letıs look at each of these 4 sub-systems so that we can make the right
choices.
Latches... The Last Thing Comes First
The first question to answer is about your latches - original or
"bear-claw"? If your original latches are in good working condition and
you want to keep them, you can. For street rods and most vehicles through
at least the '60's that means you will need more power to pull the
strong springs in those units. (A few extra tricks may be needed, too!)
Often 15-20 pounds or more of pull is needed just to overcome the latch
spring and small "can" solenoids or gear-motor actuators will NOT cut
it. We can not stress this strongly enough. Donıt let anyone sell you
parts that arenıt strong enough to do the job. Cheaper isnıt better -
better is better. With original latches, you need the power of
StreetWorks solenoids. They've been tested at 34 pounds of pull, and
have dependable power for both original and bear-claw latches.
If you have bear-claws or need/want to switch to them, then screw-motor
actuators will do the job, but don't think this route is cheaper !
Both approaches cost almost exactly the same. Make your choice
based upon what you need and want, not upon perceived cost. Going to
bear-claws and actuators may even be more work!
Actuators and Solenoids
Let's get our terms straight.
An "actuator" is anything that actuates or moves something else. We want
to actuate our latch and cause it to release and open the door. We can do
that with a gear-motor actuator or a solenoid.
Gear-motor actuators use a small DC motor and either gears or a
rack-and-pinion drive. Electricity causes the motor to turn and the gears
give us pull or push depending upon the electrical polarity we applied to
the motor. (Most of the actuators being sold are originally door lock
units. This is why they donıt have the design strength to pull most older
latches.) Motor size and gearing determine their strength which is
usually about 12 pounds maximum.
We can also use a solenoid, which is an electromagnetic actuator
devise. Electricity running through a wire coil creates a magnetic field
which acts on an iron core plunger and gives us pull. Wire size and
length, number of coils and plunger size determine strength. StreetWorks
Hotshots
solenoids have been independently tested at 34 pounds of pull. Over
2-1/2 times that of a typical actuator. But donıt assume that all
"solenoids" are this strong. Small foreign units on the market mislead
many people and as one of our customers said, "they donıt have the
strength to flick the ash off of a cigarette!".
Your choice should be for the type of actuator, screw-motor or
solenoid, and size that will give you the strength and the
depend-ability you need to open your latch. Quality screw-motor
actuators and solenoids each have a job that they are meant to do.
Know what you need and ask the supplier how strong their unit is. If they
donıt know or canıt give you a number in pounds of pull (not inch-pounds
or foot-pounds which are incorrect measures!) you just may be buying
trouble.
Both types can burn out if ask to do more than they are capable of
doing (not burn-up, as some sales people want you to believe -
please, never "buy" fear). The three reasons for actuators or
solenoids burning out are - (#1) The triggering system (switch) sticks
"on" or a cheap switch allows current to leak by and overheats the unit.
(#2) The unit is "over-used", that is, if an actuator is being asked to do
more than it can and the switch is triggered repeatedly or held on for an
extended time, the unit also will overheat. And (#3) the unit may have
been defective to begin with (hey, it happens).
Another point to consider is - what are you getting for your money? Are
you buying one piece or are you getting an entire kit? Price can be
deceiving if you aren't comparing like products. Also, does the supplier
carry a full line of entry products? You ask the questions but did they
have believable answers and provide options for you? StreetWorks has
more Entry System products than anyone else and can tailor a
system to meet your specific needs. Even our catalog has a section
on Entry System Design and is setup to visually present each of the
sub-systems. Give us a call and we will review your specifics and get you
what you need - the first time!
Triggering the Magic - Switches
Now that you have made your latch selection which has determined
the type of actuator or solenoid to use - how do you want to trigger the
magic to happen?
My recommendation to all of our customers is to try to imagine
yourself walking up to the car after everything has been done. What
do you want to do to open the door? Push a button on a remote
control key fob? Reach down to push a button or pad under the running
board or fender? Have a key ring magnet to swipe past a hidden switch? Any
of these are possible at StreetWorks and each one provides a completely
different feel and look to accomplish the same thing. So, let's review
each type.
The simplest and least expensive triggering switches are buttons.
Back in the '50's, starter buttons would be used. But they aren't
waterproof nor all that good looking. Todays answer is waterproof buttons.
They're small and attractive and can be used with relays if you're
switching solenoids that use more amperage, or without for actuators.
(Remember that our solenoids have 2-1/2 time the pull of gear motor
actuators. They get that strength from amperage, so switches for our
solenoids need to be able to switch about 20 - 25 amps.)
A couple of new approaches to switches are seen in StreetWorks MagTech
Magnet Entry System and PressTech
Touch Pad Entry System.
MagTech uses a key ring magnet to activate a hidden reed switch.
The magnet is encased in a black plastic to prevent any scratching of
paint. Just swipe the magnet past a hidden reed switch (a small
cylindrical item with wires) and the door opens. Now this is really
magic ! People can watch you trigger the door and still not realize
how you do it. Since you donıt have to point the magnet at the switch like
you would with a key, you can be very casual with your keys dangling from
a finger or hidden in your hand as you trigger the door. Since it uses
magnetism, MagTech doesnıt work through steel but it works through glass,
plastic, fiberglass, aluminum, body filler... there are numerous places to
hide the reed switch. Just ask for ideas.
The PressTech
Entry System is a modern version of waterproof
buttons with a twist. The switch is a thin touch pad about 3/16" thick by
1" square. To trigger your doors you simply press on the pressure pad
switch, it triggers the solenoids and you're in. But even better than
buttons, because they're thin, they can be hidden under upholstery or in
some very inconspicuous places - like behind a flexible panel, inside a
mirror housing or gas fill door... let your imagination run wild.
O.K. Let's do a brief review. So far we've talked about triggering our doors with waterproof buttons,
with a key-ring magnet waved magically past a hidden switch or with a
touch on a pressure sensitive pad. All pretty trick stuff to say the
least. But this is the age of electronics, so let's look at still another
way to trigger the magic.
Triggering with Remote Controls
The rage of the '90s - Remote Controls. Let your fingers do
the flying with the speed of radio frequency! They have become
standard equipment on modern cars for door locks and for alarm systems
just to name two uses you know. And it's a great way to trigger your
electric latch release, too!
We are proud to carry one of the finest lines of remote controls made
today. Simply push the little button on your key-fob transmitter and the
door is unlatched from close range or up to about 50 feet away. (Note that
you probably won't want to open your door from that far away. We are so
used to reaching out for the door handle and opening the door that it
usually feels best to trigger the remote just as we are reaching for the
door to pull it the rest of the way open.)
These units have over 4000 codes for security. Choose a two function
unit to open both doors (relays are needed to work with our Solenoids) or
add a third function for the trunk release or for a remote battery
disconnect . Or go big time with an 8-function remote designed to
run power windows plus door releases and with additional functions for
trunk release or a power trunk lift.
If you are leaning towards a remote control it is very important
to know what power "accessories" you want to have in your car and which of
those should be controlled by the remote. Power windows need 4
functions to run 2 windows, doors need just 2 (both for a 2-door of
course).
Plan your project and it will be what you want it to be!
Now lets us show you some new stuff.....
StreetWorks Trilogy
3-Function Remote Controls
We do our best to listen to our customers.
Many of you said that you want a remote to operate the two doors PLUS a
trunk release or battery disconnect. You got it!
Here is the StreetWorks Trilogy
3-function remote control. The features that make it special are the
"Trilogy" power of "3".
- 3-functions to open two doors and a trunk
release or battery disconnect.
- It includes the 40 amp relays
needed with all other remote controls to power our solenoids. And,
- It has two 3-button key-fob
transmitters so that each function has it's own button - you don't have
to play "video games" with your thumbs trying to push two buttons at
once.
Since we have designed this unit ourselves, we
were able to incorporate the relays and still price the Trilogy at
the same price as comparable units without relays. We also have a separate
power feed for channel #3 - when used with our remote control battery
disconnect, that allows you to retain power to remotely activate the
disconnect while shutting down all the other systems including the doors.
It's a great security feature and it's as easy as pushing a button!
We would be remiss not to stress the importance of where you buy
your system. After all, there are lots of companies out there that want to
sell you parts. BUT...
- Do they carry a full line of Entry System Products? Or do they just
have some actuators and not even any switches to trigger them?
- Do they have choices of switches and remotes? Or do they just have
one remote control, take-it-or-leave-it?
- Do they give you that important choice between actuators and
solenoids? Or do they tell you that their actuators with 12 pounds of pull
will open anything, because thatıs the only thing they have to sell?
- Do they offer a complete kit with nearly all the parts you need? Or
do their parts come with nothing - no nuts, bolts, screws, wire,
instructions... nothing?
- Do they have a guarantee? A return policy? In writing?
A cheap price can end up costing you a lot in aggravation and dollars.

Review Time...
O.K. We've pretty much put it all together now but let's review -
(1) we know what latches we are going to use, original or bear-claw, and
that determined (2) which actuator we wanted, gear-motor or solenoid. And
then we thought about how we wanted to trigger the units and picked (3)
our type of switches. We've got it all!
Well... yes and no. Those three items will give
you a fully operating and quality system. But you may want to consider two
additional items that fall under the sub-system of...
Safety Systems
The subject of Safety Systems really covers two distinct items,
Locking and Mechanical Back-up Entry. Most original latches have a latch release mechanism and a separate
locking mechanism that keeps the latch from working (and should be
disabled when converting to electric!). But what about electrical systems?
Regardless of the triggering system, your
electrical latch release system can be locked, too. But in this case you
need an electrical lock such as our Keylock Electrical
Switch.
Put into the electrical circuit for your buttons, MagTech, PressTech or
remote control triggering system, this keylock shuts off power to the
system and locks the car. Safe and sound. And the key is removable
in either the On or Off position so that you can leave the system in
either mode as you want.
The second Safety subject is easily summarized
as follows: in case of electrical failure, give yourself a mechanical way
of getting OUT of the car, fast, and a way to get INTO the car or
at least to the battery if necessary. Batteries do go dead and accidents
happen. Give yourself a safe exit and a back-up to get in.
For many people, keeping the original inside
handles gives them the mechanical way to get out. But if you've gone to
power windows and a clean looking door panel, you'll love StreetWorks Neat
Nobs Latch Release Kits for bear-claw latches. Either way, don't allow
yourself to be trapped inside your car by a loose wire or worse.
Providing a back-up way to get to the battery
depends upon your car's situation. Is the battery under the hood? in the
trunk? back of the seat? How could you get to it? For example; your
battery is under the hood and the only release is an inside-the-car cable
release. Easy! Install a second cable or rod that can be tripped in an
emergency. Sure, you may have to get on your back under the front end to
reach it, but it's just for emergencies and you don't want it to be too
easy to reach anyway, for safety sake. The same type of approach can work
for batteries in the trunk. And if all else fails you can put cable
jumpers on the battery.
Emergency back-up for getting into the car might
include access through the trunk and a removable panel or another way of
mechanically tripping one latch with a cable or rod.
You shouldn't need both battery and access
back-ups but planning ahead for possible problems will prepare you for
that "if-and-when" situation that none of us wants to have to face.
Trouble Shooting Common Problems
To conclude, letıs look at some common problems that arise in
electrical Entry Systems.
Original Latches need to be "gone over".
No ware, catches or drag allowed. Check the latch "tongue" bumper stop -
it may need to be replaced to prevent the tongue from traveling too far
out of the door. 1/4' - 3/8' overlap of the striker is sufficient. If the
return spring is too strong or pushes on the tongue even in the "closed"
position, cold-reverse bend the spring so that it closes the latch but no
more beyond that. A latch booster spring can make a big difference, too.
Make sure the surfaces where the tongue and striker plate hit are smooth
and lubricated. You may need to back angle the striker edge with a file to
eliminate pinpoint contact and the resulting friction.
Bear claws need lubrication, too. Get it
inside where the trigger plate and rotor contact each other and use
grease, not a liquid lube that will evaporate.
Tight door gaskets will create problems
for original or bear claw latches by putting the latch under extreme
pressure.
Whether you use a cable or rod to connect the
actuator/solenoid to the latch, leave some slack in the connection.
Too tight and the unit can bind. They all need a little "jump start" to
get their maximum power.
Youıre trying to use a $39.95 remote to power
strong solenoids... get real. Make sure that every piece of the
system is matched. Cheap switches will burn out or can cause actuator/
solenoids to burn out, too.
And the #1 cause of problems... bad grounding.
Don't expect to ground to the door steel and get good current flow.
Whether your hinges are lubricated or rusty they're not good conductors.
Run a full size ground wire back into the cockpit and attach it to body or
chassis steel. Trouble shoot with a Volt-Ohm meter - one component at a
time to isolate the problem.
If you have other questions or want to place an
order give us a call at 860.859.0513. Thanks !
