My car keeps locking and unlocking itself, and whenever i unlock the car manually the alarm goes off. This happens even though i lock the car manually. It all happened after i pulled the ecu-b fuse.

After Market alarms are always full of issues especially when the batteries are disconnected of the car batteries are disconnected.

Find a Viper Alarms installer and take it in for reprogramming with their pro grade scan tool computer.

Try unlocking the door manually with the keys. If problem still happens. Your door or hood switch may be defective. They will send a false signal to the alarm that indicates one is open.

Sounds like the key fob is going bad and needs replaced.

hi Alan

what procedure you are doing for remote matching?
try this one and let me know.

1 Unlock the car, get in and close the door

2 Switch ignition on

3 Press the door lock button on the dash to lock the car

4 Press and hold the door lock button on the dash, the alarm will beep

5 Keep holding the door lock button on the dash, press and hold the lock on the remote,

the alarm will beep

Repeat (5) for the other remotes,

6 leave the door lock button on the dash, the alarm will beep, switch ignition off

You will needs to think of it this way. Once you set your alarm it is looking for the corresponding signal to disable itself. That comes from the fob. If you don't use the fob and just use the key, the alarm system is doing its job and alerting you since it has not received the disable command from the fob. Either lock the door with the button when you exit the car if you want to use the key or use the alarm fob. This will also happen if you use the car manufacturers fob to unlock the car if you have locked it with the alarm manufacturers fob.

Hope that helps - I have hidden all of my original car fobs to help alleviate this problem!

Sounds like you have a short where you are moving the wiring. Remove tape/wire loom from the harness and see if you find bare or broken wires. They are very prone to do this in the wiring between the door and the body. Repair problem wires and you should be okay. Alarm is most likely being triggered by the same short. Happy hunting!

replace both door lock actuators to fix problem.

This car has a feature that can automatically lock your doors after you leave your car unlocked for a period of time – this can be turned off. I had the dealer do it but I am sure if you check the manual it can show you how to do it yourself. The alarm and locks on this car are very sensitive and often break so if this problem isn't resolved by deactivating the auto lock then I would have a mechanic look into it.
