I just bought a 96 Bonneville that came with an aftermarket remote start/keyless entry but the keyless entry was not hooked up. The car also has factory keyless entry according to the RPO but it did not have any key fobs. I was wondering, is it possible to connect the aftermarket keyless entry into the factory system in order to keep the progressive unlocking feature? Thanks.

Yes...you would need the instructions for the aftermarket system and then you could properly hook it up.

Um Bill, I'm going to disagree with you on this one.

Er ooopsie?

Did I Lash out a post too quick. Progressive locking as in????? Many alarms can lock and unlock via a gear selector input and or a timed ignition input as well. It would be very much like the type of locking unlocking of the factory system.

I think he is after the push once for driver door unlock, push twice for all door unlock.

yes...very possible on certain aftermarket systems.

Problem is..we don't know which system he has.

yes, possible, but this came with a 96 SE. Chances are not very good that a highend remote start would be left on when traded. But, we are guessing at this point, yes.

sonoma_zr2 is correct, I would like to push the button once for driver door and twice for all doors. After hunting around I found out that it is an old remote start that has been discontinued. It is a TRC remote. I was able to find directions for it and there are three wires associated with the door lock. They are 12v (+), Unlock (-) and Lock (-). Is it just wishful thinking to be able to tap into the factory system? Thanks.

You could tap in and have it lock/unlock...but the one tap driver, two tap the rest...isn't happening.

I don't believe there are any aftermaket systems that "tap into" the factory remote system. They all work by tying into the individual system (door lock, power window, vats, starter, etc) circuits.
