Go to an alarm shop and see what they have. Compustar, Viper, Clifford...all good stuff.

You can add on bells and whistles until the cows come home. One way remotes, 2 way pager types, Auto start, shock sensors, trunk poppers, remote window regulators, temperature sensors...the list goes on and on.

There is none. The timer is built into the computer and not adjustable. It's burned into a chip somewhere as part of the program.

All aftermarket alarms do this same thing, and as far as I can remember is not something you can turn off.

The reason alarms relock after a timed period is a saftey precaution. In the event that the unlock button is ever pressed on accident (in a pocket or purse) the alarm will auto re-lock if no doors are opened in order to keep you from accidentally leaving your car unlocked. To me this seems like a valuable feature, especially on aftermarket alarms that have much longer remote ranges.

The only way to defeat the timer is to open a door after unlocking, or trick the alarm into thinking a door has been opened.

You can use a relay to temporarily connect the door pin wire to chassis ground to fool the alarm/car into thinking the door had been opened, canceling the re-lock counter.
The hard part will be finding a suitable trigger to activate the relay when you unlock the car. The only thing I can think that could work would be the unlock trigger wire (under the dash). The trigger wire is a low current negative (chassis ground) which could activate a relay, the only issue is it has a very short pulse (Im talking milliseconds).
I cannot say for certain, but it should work. The relay should then click on & off which would give the door trigger wire a short ground pulse telling the car the door had been opened & closed real fast.

A car stereo place could do this for you, and would probably need the car for a couple hours ($50~$100 cost) in order to test and make sure it is working properly.
A lot of work to bypass such a trivial thing and is probably why its never been posted on here, but it is possible.

None of my aftermarket alarms ever did the auto relocking thing. I've had a couple Compustars and a Clifford. Hit unlock/disarm and they stay unlocked.

My one way Compustar in my Element right now does the same thing. It's not an alarm, but an autostart. It locks/unlocks the doors as well as starts the car if you shut it off so it arms the autostart.
