Alarm goes off when key open the door

I lost my keyless remote to my 2003 chevy mini van to unlock my door. When I use my duplicate key to open my door the alarm goes off. I bought another keyless remote for the key that I have to use for my van. I went to the GMC dealer to get the keyless remote re-program and the dealer can not re-program the keyless remote. They tried everything to get the keyless program and nothing seem to work. The alarm constantly goes off when I open the door and also when I insert it into the ignition. What can be the problem that they cannot program the keyless remote? I been at this dealer for 3 days and they said that I would have to replace the Body Control Modular (BCM). This is costly. I biught a new Audi key fob and followed the directions to reprogram it but when I initially put in the first key and turn the ignition there is no problem. However when I press the new spare key button to set it it is supposed to hoot the horn but instead it causes the alarm light to flash i.e. the emergency flashers come on instead of the horn hooting.
I am also stuck
Please can some eone suggest a solution?

Try disarming the car from the trunk. Sounds like the door lock switch is not deactivating the alarm, which it should, with or without the remote.

Bought from dealer with no keyless entry. alarm activates when doors are locked with power doorlock system. alarm sounds when we open the door. how do we de-activate the alarm before unlocking the door?


Opening the drivers door with the key is supposed to shut down the factory security but the drivers key cylinder usually goes bad. You will have to unlock the rear tail gate lock cylinder with the key and that will shut down the factory security, before opening the drivers door.Your other option is to have an aftermarket keyless entry system installed, which will open the doors remotely while shut down the factory security at the same time.

My keyless entry remote stopped working so i had unlock the door through a cracked window.... the alarm went off, but when i started it, the alem didnt stop.... now when i dont lock it and open the door or...


yes the remotes do have batteries. how ever that might be your problem or the remotes lost its code for programing. step when turning alarm off---- if its a factory alarm put the key in the drivers door when the door is closed and lock then unlock it thats the manuel shut down for factory. step 2------- aftermarket alarm. look for a valet switch most likely it would be installed by the driver kick panel or by the under dash fuse box. when u find it put the key into the ignition. turn it to the run position. within 3 seconds press and hold the valet switch for 3 to 5 seconds you should here a confirmation chirp and the led light will stay on solid and wont blink give it a world let me know what happens

Alarm goes off when key open the door


Dealer is correct that you have too replace the bcm, so i would tell you to call junk yard and get one. Cheap $ 50.00 put it in by yourself. Right hand side of the glove compartment. behind the fuse box with couple connectors on it, or have some person with knowledge to do it.

Lost keyless entry remote


The fuse for the alarm is under the hood. Give a good look and you should find it. Once you have pulled it it will deactivate the alarm I am not sure if this is exactly your problem since you said that the car wont start.... but it is worth a try.

Keyless entry stopped working on 05 cobalt now i have to unlock door with the key and when i do that the alarm goes off. Help


Lock all the doors from the inside (with all the doors closed), unlock your driver's door by manually lifting the lock, then press it back down after you are out - this will prevent the alarm from sounding when you use the key to unlock the door.
