Hi All,

I have a 2010 Dodge Charger SXT. I had a compustar alarm installed (w/ Blade unit - I Believe the ADS-BLADE AL) and I've been having having a problem with the door locks. When I engage the alarm, the alarm always engages, but sometimes the doors do not lock. I must disarm and rearm the system for the doors to lock once every 2 or 3 days. Also, sometimes they trunk does not open and I must unlock it twice. I have been to my alarm installer and they have replaced both the compustar alarm module and blade unit (which I believe talks to the vehicles data BUS) to no avail. Any ideas what might be happening?

Can you verify that they are using a CAN-BUS module? Without the module you will need resistors to lock and unlock. Try double pulse unlock to see if that will patch the issue.

On some cars the locks wont work until the dome light shuts off.  If it is wired to lock/unlock/trunk via data, it may need to be hardwired to the locks/trunk.

Thanks, it wasn't the dome lights, but I went in last week and they hardwired it to the locks & trunk opening, so far, so good! :)
