GT Central Locking / Alarm doesnt open door
I wonder if anyone cna help with this. This morning I unlocked the GT with the key as normal but I didnt hear the beeps as usual to disable the alarm, went to the door and it was locked, tried the open on the key again and it seemed to unlock then instantly lock before I could get the door open. Tried the key in the lock and that did same thing so ended up opening the boot and climbing in to open door from inside.
Has anyone else had this and what was the cause? Car is 2006 1.9 GT. Could it be the remotes batteries or maybe even the main battery failing? I got the car in Feb with only 24,500 miles on and have since done a couple of thousand miles but to me the car always sounds a touch sluggish as if the battery is not that great.
ANy thoughts appreciated and if it is the remote battereis, what sort do I need.
Currently Alfa GT 1.9
Previously 1.4 Fiat 500
Before that 3 156's amongst 30+ others
