92-95 Horn chirp with door lock
I asked the question here but still looking for an answer.
Can you use a Tech scanner to make the 92-95 cars chirp when you lock the doors? |
Very good question. I'd also like to know.
|
I am thinking no. Ditto on making the lights flash as well.

No, It cant be done as far as I know. Thats all controlled via BCM. Unless you could find a BCM from a car of that era that did have that option, but, there may be some compatabilty issues.
Im sure Caddiies had that option |
I didn't think pre-96 cars had a BCM.
I was thinking maybe a pulsed relay setup could do the light flash, along with a 555 timer set to 3 seconds. Any thoughts on a setup like that? |
Mine on the 94 chirps, but I have an aftermarket fob.

Has to be
Trent..it might be possible with a Tech1 or Tech2.. like the perimeter lighting I found on the 97 with the Tech 2. Problem is..you won't know until you get the tool and go looking for it. |
Trent, yes it is indeed a part of the aftermarket keyless entry
|
Yes, not an aftermarket alarm, but aftermarket keyless entry.

Thinking about this more last night.
It might be possible to tap into the RFA box where it outputs the signal to the locks. Add in a diode and then a relay to the horn. That way only when you lock the doors with the remote..you get a chirp. |

The light flash idea is pretty good, just to let you know it's armed. But as long as you have a good fob battery, it shouldn't be an issue.
Isn't there a door lock relay? Just take your signal from there and run it to a separate relay for a dedicated horn or chirping unit. I think a light would be appreciated more by the neighbors. Just my $.02 |
I just skipped right past half this thread to post the answer. Yes. You can have the horn beep, but easier even would be to get a third horn (my car has a high & a low) and rig it to the lock system.
You'd need a couple things, and since you don't want to use the voltage from the locking system to honk the horn, this "extra hardware" that was referred to to draw power from somewhere else may seem a bit alien. However, though, don't worry much about the grotesque wiring that is necessary because you & I have the same cars, and I'll just set this up on mine to show you. |

I think an inexpensive aftermarket alarm system is the least expensive way to do this. My wife's 2001 GP GT does the horn toot with the second press of the door lock button on the factory keyless entry fob. My car chirps its Clifford alarm when I operate it. Between the two, I vastly prefer the alarm chirp and find the horn toot to be completely annoying. Also, I can do a stealth "silent lock" with my Clifford fob, I don't know if you can do that on the factory keyless entry for the models like my wife's 2001 GP GT.
It comes in handy to not annoy the neighbors late at night when locking the car. |

Just my $.02 And on the annoyance factor, why do you think it wasn't done that way at the factory? :lol: I still think a visible alert would be preferable to an audible one. And with some sort of dedicated LED, it wouldn't draw as much juice as a horn. |
Ok, Gravenge does the same damn thing everyonce in a while, and this is with everything OEM.
