99 M3 Convertible Keyless Entry Problem

[SthrnX5Boy]

Bought a 99 M3 COnvertible today with a hardtop. The keyless entry will not lock or unlock the doors. It does however chirp 3 times when you press the lock or unlock buttons. Anyone have any idea what could be causing this? First thing I though of was the hardtop. Wasn't sure if the car thinks the top is down and won't lock....doubt thats it, so any help would be great!! Thanks :dunno:

The three chirp means one of the doors/trunk or hood is open (or the car thinks it's open). Double check nothing's blocking the trunk, and check all the closed switches. I think it will lock even with the top partially down, I can check today if you need me to (I know it will lock fine with the top fully stowed).

Thanks Josh...I'll check it out today and see what I can come up with. :thumbup:

also if someone changed to an aftermarket radio, removed and incorrectly installed the factory radio, they may have knocked the switch loose on the rear of it.
