Why Isn't Your Key Fob Working After a Battery Change?

But why does this happen? Top St. Louis Locksmith has some insights and solutions to help you out.

Why Battery Replacement

Firstly, ensure you understand that replacing the battery in your key fob doesn't mean it will automatically start working again. It doesn't work that way. In fact, the key fob might sometimes need to be reprogrammed after a battery change in order to work properly and effectively.

One reason your key fob may not work after a battery change is due to a programming issue. Sometimes, the key fob needs to be programmed to communicate with your car's security system. If the programming is incorrect or has been lost, your key fob won't work at all.

Damaged Key Fob

Another possible reason your key fob isn't working is due to a malfunctioning or damaged key fob. If the device is damaged in any way, such as if it's been dropped or exposed to water, it may not work even if you replace the battery. In this case, you may need to replace the key fob and the battery together.

Apart from programming issues and possible damages, the car security systems be the culprit. There must be a synchronization between the key fob and your car security systems, if any of them is faulty your key fob won't work.

In this case, you may need to bring your car to a dealership or a trusted locksmith like Top St. Louis Locksmith to have the security system checked.

So, what’s the solution if your key fob isn't working after a battery change? Flat out. The first thing you need to do is try reprogramming the key fob.
