Hey guys. I got a door lock actuator kit. I would like to install it this weekend. Now i'm fairly knowledgeable with electronics, so i don't think this will be a problem, however, here's my question. The stock alarm senses if the door locks are unlocked without a key, correct? So if i use these actuators, the stock alarm will go off every time i unlock my doors with the aftermarket alarm output channel, right? Any way to bypass this/ THanks

Anyone??

Yes there is 2 ways to do this

1) close the door and arm it like normal, then the stock alarm wont set, it only sets with the door being locked while its open

2) split the unlock wire (-) pulse from the keyless/alarm that you are hooking up to the lt green/blk at the theft module behind the glove box and the other goes to the relay that controls the door lock

Are these typical 2 wire actuators you have w/o relays?

Use 5 point bosch or equil. relays, you have to use two relays

86 and 87 go to 12 V on both relays
85 on one goes to lock (-) pulse and on the other relay 85 goes to unlock (-)
both 87a's go to ground
30 goes to one wire on the actuator and the other 30 goes to the other

I hope I didnt screw that up too bad, I got a shitty way of explaining, if I dont re see this post just email me

These are so simple to do, if doing an alarm, you can grab hood pin, trunk pin, door pin, dome light surv, etc all from the theft module. Used to do these all the time and it took maybe 1 1/2 hour tops to do a full blown alarm with window rollup.

all to be gotten at the theft module:

door trigger blue/white (-)
Trunk/hatch trigger green (-)
hood trigger brown/white (-)
Factory arm green/red (-) (Of course it wont arm without the door being open)
factory alarm disarm lt green/blk (-)

parking light flash can be gotten at the glove box bulb (+) trigger

 

Only if lock them from the inside!

Yes the alarm will go off every time you unlock them with the aftermarket alarm. You need find the micro switch which is located in any of the doors; everytime you lock you doors from the outside (by using the key)this micro switch is activated.

I am almost sure that a ground output will deactivate the micro switch. Use a diode in series with a a cable coming from the aftermarket alarm supplying ground output every time you (and ONLY) deactivate the aftermarket alarm.


- Micro switch- <-----xxdiodexxx <----- -new alarm-


xxxxx represents the cable which will supply ground (I think, you need to verify that) from the aftermarket alarm to the micro switch.

If you have questions please let me know!

DAMN ASCII

 

yep KNONFS and mike got it right,

Either use a relay or diode off of the keyless entry/security systems unlock wire and tie it into the key sensor wire (ususally green/Black, but it depends on series), so that every time you unlock with the remote it will think you used the key in the door to unlock the car.

 

Thanks alot guys. I was just looking for the wire on the stock alarm that will disarm it. I want to keep both alarms (one as a backup) ... the actuators i have are the 5-wire ones, and they come with a control module (such that both door locks operate at the same time for convenience, since i don't have a PDL button)... So here's what i'm thinking... wire the actuators as per instructions, with the controller module hooked up to the alarm... take the lead from the alarm that sends a (-) unlock pulse, and hook it up to factory alarm lt green/blk lead. Sound good?

 

Yelp, your right that will do it...

If you want to arm the factory alarm with the aftermarket one, when exiting the vehicle , arm the alarm and shut the door quickly... When you come back to the vehicle, press disarm and it will disarm the factory alarm and your alram too

 

Sweet. One more quick question Does the stock alarm have a constant positive/negative? So that i can wire up the control module to it.
Thanks

 

I put in an aftermarket alarm wired to lock my doors when armed, unlock when dis-arm. Arming after I close the doors, only the aftermarket alarm arms. Factory alarm does not as it is no different than locking the doors from the inside.

However, if after locking the doors via arming my aftermarket, I then open and close the trunk (rear hatch in your case), my factory alarm will then arm. So, when I then disarm my aftermarket alarm (thus unlocking the doors without the key), THEN the factory alarm will go off.

Actually, I see that as a good thing. Well equiped car thieves can use a "black box scanner" that will disarm my aftermarket alarm. However, if he/she does so, the resultant unlocking of the doors sets off my factory alarm.

Stealth secondary protection!!!!

 

Hey man, good luck on getting that problem fixed! This is good info....

 

It all depends how the aftermarket alarm was wired, if it was wired to the oem then this should work:

Here's a solution (not the right one, but it will work), before closing the doors make sure that BOTH locks are closed, then activate the aftermarket alarm, aand then close the door (make sure you are pulling the handle so that the lock stay locked).

Try it and let us know!

 

Well guys i have done it. I put a diode on the unlock (-) pulse of my aftermarket, ran the wire to the other side of the car to disarm the stock alarm when the aftermarket alarm is disarmed. This way, when the door locks are popped open with the aftermarket alarm still on, both of the alarms will go off. The only way to disarm BOTH alarms is with the remote. I will be removing the rods for the door lock cylinders, and possibly filling in the hole for them, so as to confuse the theif, more than anything, and to prevent him from prying my door up once he realizes the locks are electronic. Soon, i'll get door poppers too so i'm sure the fact that the car has no door handles will confuse the theif enough

 

Now for the FUN part, make sure you can disarm the stock alarm from the rear, AND that you have a GOOD\RELIABLE aftermarket alarm. You really don't want to do the setup mentioned above and then have your aftermarket alarm fail on you......................it happens and and it happens ALOT!

 

It's a Viper 300 (before DEI replaced it with the ESP model) so it's not the bitwriter one. I love the alarm. It's awesome, and has never failed on me. i just need some sirens with battery backup now. But everything is wired up with the alarms... working beautifully. If anyone wants a proper write-up, email me, i'll be happy to do so.
