3rd Party Keyless Entry DIY (Why Not?)

[antny]

OK guys need some help now. New actuator came in and installed. It is not moving at all when I hit the trunk button. The light on the dash is illuminating when I hit the button so it is getting a signal from the key. I would much rather install a unit like you guys have if it will send the signal to the actuator for it to work instead of paying a labor hour at the dealership that would cost me way more than the system to go in.

Any ideas or suggestions?

Doors unlocked and you are holding the trunk unlock button down for more than three seconds?

[antny]

Yes Sir. On Renntech a guy had the same problem and he said he took in into the dealer and they had to recode the ECU an it worked after. I am obviously trying to avoid that if possible.

Here is that thread.

Yes you can add the 3rd party keyless remote like particle wave and I did. I actually cut the blue black wire away from immobiliser

[antny]

You cut it away from the immobilizer and wired it direct to the aftermarket unit directly?

[healthservices]

Well I used a relay as the first aftermarket unit could not take the load (it fried) and I did not want the immobilizer to be in harms way. second one I used a relay and no issues. Some of the units like particlewave bought have a relay inside and can take a load, I just did not want to chance it.

[antny]

I just ordered the one you bought. Can you give me any help on what relay to buy and how to wire it? I have ever installed relays in all the things I ever have done with cars.

Thanks bud.

Not a problem. Pretty much standard relay. That can be bought. I just happen to have one. But will find one online so you can see

But just look up alarm relay and look for one that looks like that, get one with a pig tail so you don't have to source a bunch of wires and connectors.

[antny]

Dumb question again. Which wires go to what on the relay?

[healthservices]

delete this one

[healthservices]

try this one instead...

87 jumps over the red wire it does not connect to it.

Looks like healthservices already drew up a diagram

In his diagram, where it says "to aftermarket keyless signal wire", attach your purple wire from the keyless entry module.
I'd do what he did and mount the relay in the trunk, right next to the actuator. This seems easiest.

You'll cut the blue/black wire in 2 places: at the immobilizer where you'll connect your purple wire, and at the actuator, where the blue black/wire coming into the trunk will now be connected to your relay (pin 85), and the switched ground from the relay (pin 87) will be connected to the blue black wire on the actuator.

I actually have an identical relay to his one you posted. So let me break this down because these diagrams make my eyes cross lol.


Cut the blue black wire from the immobilizer.

Connect AM trunk wire to the blue black wire and connect to pin 85

Connect 86 pin with a tap to the red wire

Connect pin 87 to the blue and wire

Ground pin 30

Did I get that schematic correct?

I really do appreciate it the help. I can and have done almost every other thing about working on a car and never have wired a relay lol.

Its funny how some of us are visual and others are not. Which can be a good thing

lol that is true. I am visual on 99 percent of things besides electrical stuff. Wiring diagrams confuse the ever living hell out of me lol.

Cut the blue black wire from the immobilizer. leave immobilizer end disconnected, connect the other end to door lock signal wire from keyless entry



In the trunk....

Connect the unconnected blue black trunk wire to 85

Connect the unconnected blue black trunk wire from actuator to 87

Connect 86 pin with a tap to the red wire

Ground pin 30

Connect the red wire.

[antny]

Perfect. Thanks bud you have been a life saver on this one. Maybe my only complaint on the car will go away now.

With these cars there always something that can be improved or fixed. Its just... when do we stop?

NEVER!!!

Nothing left to fix on mine, but I'm always looking for things to tweak or improve.

This keyless entry was one of my favorite mods due to ease and usefulness. My "hand activated" storage shelf lights are a close second. Of course, I'm quite fond of the headlights and side markers, as well.

Just...can't...stop!
