Reported Problem: Do I Have to Reprogram my Remote FOB after Replacing the Battery in it?
Answer: We get this call almost every day. A properly working remote will not lose it's programming from just changing the battery in it. The number one indication that your remote just needed a fresh battery is when you had to get closer and closer to the vehicle to unlock the doors or activate any other features controlled by the remote.
But if your remote suddenly stopped working or worked intermittently from any distance and then stopped working, odds are you have a worn-out or damaged remote and need a new replacement. With the exception of some "cloning" type remotes, no factory installed or aftermarket remotes lose their programming.
They are designed with what is sometimes called a non-volatile memory which retains the remote's operating frequency and does not require it's memory data to be periodically refreshed or reprogrammed due to low or complete power loss.
