If your remote's stopped bleeping it probably needs a new battery. Battery voltage drops with low temperatures.When I operate my remote to unlock or lock the car, the beep stops working when its cold (like below 0 celsius). The flashers still blink and the doors lock and unlock, just no beep when its cold. Anyone else had this issue? Any ideas?
The OP's post wasn't clear whether it was the car or remote not beeping and some car remotes do beep. However, you omitted the rest of my post.................The remote does not beep; the car does... or should.
