Car Key Batteries

Car key batteries typically last for around three to four years. So, if you’re noticing that your battery is either dying, or completely dead, it’s time to start thinking about a replacement.  

Our range of replacement car key batteries at Halfords covers all of the common car brands you’re likely to find on UK roads, so we’re almost guaranteed to have a battery that’s right for you. 

If you already know exactly which battery you need, browse our range above. If not, pop down to your local Halfords store with your car keys and our friendly team will be happy to investigate for you. Changing a car key battery can be a little tricky, which is why we also offer a fitting service for an extra £5 charge.
