I have a 1998 Durango SLT with a 5.9. Quite a while back the key fob quit working (no not the battery) but no big deal I just used the key. When you use the power locks to lock the vehicle when leaving it arms the security system and when you use the key to unlock your door it is supposed to disarm the security system. My problem is the key will not disarm the security system and the lights blink and horn beeps and the vehicle won't start as a result. Any thoughts or suggestions would be appreciated.
The key does disarm the security system, I have been doing it for months. If I unlock the door (after using the power locks to lock the vehicle) from an open window by pulling up the lock manually the alarm would go off after opening the door and I would have to use the key to turn it off. I have not noticed any other electrical problems. I tried disconnecting the battery today hoping it would reset somehow but that did not work
Unfortunately the reset procedure did not work. When this problem started my driver door was frozen and I had to use a lighter on the key to unfreeze the "key hole" to unlock the door. I am going to get the vehicle into the garage and warm it up hoping something is frozen (yea, fat chance) and try again.
I finally broke down and took the truck to the dealer . It turned out to be a wiring problem with the security system. "Only" cost me 300 bucks (not bad considering I was thinking worse) and am on the road again. Thanks for the help.
It just happened to me couple days ago. I unplugged the battery, waited 10 minutes or so, locked all the doors, connected battery, and unlocked the drivers door with the key...it beeped 3 times, and it started...
