Car has a keyless entry.When i press the unlock button,all of the doors unlock but in about 10 seconds all of the doors lock again buy themselves.Can anyone tell me how to fix this problem?

Anybody!

try going to the alarm manufactures web site, or look at the book that came with the alarm. since the 420 didn't have that from the factory i would guess it is aftermarket

My 420 has a factory alarm! The p.o installed an aftermarket system[i quess the factory alarm malfuntioned].If i did away with the alarm,will the problem go away? I am asuming you think the problem is in the alarm.

Still don't know what to do about this problem.I do not have the alarm manual so i am lost.If it is the alarm,will the problem go away if i disconnect it?

If you disconnect the non-factory alarm, and your problem persists, then I think it would be safe to say that the problem is not related to the non-factory alarm.

Try it! - what have you got to loose?

The doors are intended to lock again after about 10-15 secs unless a door is opened as a safeguard against unlocking accidentally by pressing on the keypad.

This problem just started. The doors would stay open until i pressed the close button on the remote.What controls the close time of the doors,that could be the problem.
