ec5780 Posted October 13 Share Posted October 13 My remote control was becoming slower and slower to respond, and it got to the point where I had to press it multiple times for it to open/lock the car. I changed the battery, and at the time I remember having some trouble getting it to work. Initially it refused to work and then after pressing the buttons a few times it started to work. This was in early August. Then last week I went out; when I unlocked the car it worked perfectly but when I came to lock the car the remote control was completely dead. No gradual degradation like I had last time, and the battery was changed only a couple of months ago. I was able to lock the car with the key, but when I unlocked the car it set the alarm off! I suspect the battery is bad, but it's strange that it failed so suddenly, and so soon, as opposed to the previous battery which wore out gradually over a much longer period of time. Any thoughts? (And is there any other way to turn off the alarm if the remote control isn't working?) Quote Link to comment Share on other sites More sharing options...
Trevor Posted October 17 Share Posted October 17 I would try a replacement (quality one) in the fob and see if that improves it Quote Link to comment Share on other sites More sharing options...
ec5780 Posted October 30 Author Share Posted October 30 I measured the battery voltage with a multimeter. It was around 2.3V when it should have been 3.3! I guess one of the cells inside the battery must have suddenly failed to cause such a sudden voltage drop. I replaced the battery with another of the same batch and so far, so good. 1 Quote Link to comment Share on other sites More sharing options...
