95 Cirrus alarm problem won't stay running

On this car the Alarm system (which the car does not have) suddenly went off and the car will start and dye immediatly. No matter what you do the horn and light won't stop going and the engine will start and shut off. It has keyless remote but after taking the car to the dealer and paying them $380 was told that it needs and BCM and ECM which costs more than the car is worth. I have traced every wire from both the ECU and BCM and cannot find what system is actually stopping the car from starting. If anyone out there has dealt with this problem and has found a bypass fix to this problem I would sure apprecaite a response.

I had same problem. My car isn't supposed to have an alarm,but it went off and I could not stop it and was not able to drive it after the timing belt was changed same day. Towed it to chrysler center and the only way they could make it driveable was to disconnect the the power door locks. It didnt make sense to me but it worked. The other option they said was to replace the PCM or BCM or both,...... $$$$.
Hope this helps

i have the same problem i can start my car but it dies after 3-5 sec so if i disconnect the power door locks it should run right plz write me back
