Car key batteries

It is incredibly frustrating when your car key fob battery starts to go. It can become hit and miss when it comes to locking and unlocking the car and if you notice any little glitches it is a sure sign that your battery will need replacing. The typical shelf life of a car key battery is around three to four years, which will give you an indication as to when your battery is likely to need replacing.

Even if you feel like the battery has run out before it should, replacing the key fob itself is a costly business, so it is definitely worth eliminating the possibility of a faulty or expired battery as your first port of call. If doors are locking sporadically or if the car key fob is unresponsive it is certainly worth checking and replacing the battery. If the manual locks on the car are not working, however, then the chances are it is not a battery issue.

Battery Group and car key batteries

We, the Battery Group, are experts in the provision of top quality replacement car key batteries. As one of the UK’s leading battery providers we can supply car key fob batteries for all of the major vehicle makes and models. We offer next day delivery to the UK at the checkout.

Which car key battery do I need?

The wide variety of key and battery types can make it tricky to understand exactly which battery you need for your car’s key, but we have already categorised our batteries per car brand on our website, which will help you make sure you choose the right battery.

If you are already familiar with the size and model number of the battery you are looking for you can shop according to these details as well. If you would like to do the groundwork yourself you can usually find the details of the battery needed on the key or in the key fob, or alternatively inside the car’s handbook. This can be a bit of a chore, so please do not hesitate to get on the telephone or drop us an email with any query you might have about car key batteries.

Battery tips

One top tip is to buy a couple of batteries at the same time so that you will have a spare at home and not have to go through the process of finding out which battery you need down the line. As long as they are stored safely an unused car key fob battery will preserve its charge for many years without use, ready to be deployed later on.

In terms of opening the fob to replace the battery, the precise technique varies from vehicle to vehicle, but the basic technique involves prying open the fob and simply swapping out the old battery for the new one. Often a mini head screwdriver is required. Again, our dedicated team will be more than happy to address any of your concerns or help you with how to replace your car key battery.
