Fast, Reliable, and On-Site Key Fob Battery Replacement
If your car key fob has stopped responding, works intermittently, or only functions when held close to the vehicle, it’s likely time for a battery replacement.
At Key Smart Car Keys, we provide quick and professional key fob battery replacement services across North Devon and surrounding areas, including Bideford, Barnstaple, Torrington, South Molton, Ilfracombe, and Appledore.
We replace batteries for all types of keys — including remote, flip, and smart proximity keys — using high-quality cells that ensure long-lasting performance and reliability.
Signs Your Key Battery Needs Replacing
It’s easy to overlook your car key battery until it stops working completely. Look out for these common signs:
-
Remote only works at short range
-
Key buttons respond inconsistently
-

-

-

Our technicians can diagnose whether your issue is simply a weak battery or a deeper electronic problem — and fix it on the spot.

Frequently Asked Question
Will I need to reprogram my key after a battery replacement?
Usually not. Most key fobs retain their programming even after battery replacement. If reprogramming is needed, we can handle it immediately on-site.
How long does the replacement take?
Typically just 5–10 minutes. We test your key thoroughly before finishing to ensure everything works as expected.
What type of batteries do you use?
We only use premium-grade lithium coin cells (like Panasonic, Duracell, or Energizer) that meet OEM standards for reliability and longevity.
My key still doesn’t work after changing the battery — can you fix it?
Yes. If the issue isn’t battery-related, we can test your key’s circuit board and repair or reprogram it if needed.
Do you replace batteries for smart and proximity keys too?
Absolutely. We replace batteries for all types of modern keys, including smart proximity and push-to-start remotes.
Lost Key? No Problem.
Even if you’ve lost your only key, we can cut and program a new one from scratch using your vehicle’s lock or diagnostic data — no original key required.
Our team specialises in “all keys lost” situations, helping you regain access and start your vehicle quickly and safely.
