Taking better care of your car keys can save time, money and plans being cancelled this summer.
Taking better care of your car keys can save you time, money and stress.

Our research reveals that a car key-related callout took place every seven minutes in 2024. According to our data, two-thirds (62 per cent) of car key callouts were a result of drivers locking their keys in the car. A further fifth of callouts were for keys being jammed in the lock or ignition, whilst 12 per cent were a result of lost keys.

Our research also shows that 9.8 million drivers have found themselves unable to start their car because of a key-related issue at least once.

How about a spare key?

Whilst a spare key may come in handy, further research revealed that three million people needed breakdown assistance because of spare key failures. 6.7 million drivers claim they don’t have a spare key, highlighting how many motorists are at risk of being caught short if their car key is lost, misplaced or damaged.

Seven per cent of drivers have had to call out a technician due to key-related issues, and five per cent have had to break into their own car to retrieve a key.

Replacing a lost car key can be a costly business

Did you know that the average cost of replacing car keys is now £340? Prices vary depending on the make and model of the car, but vehicles with advanced keyless entry systems can cost even more. It shows that simple precautions can help save time, stress and of course money.

How you can take better care of your car keys

To help you avoid key-related breakdowns, John Price, our Technical Lead Engineer shares the following advice:

  • Promptly replace the batteries of any failing car keys. When a car key is running out of battery, it will become glitchy at first before failing altogether. Spot the signs early and make sure to replace the battery before it fully runs out to prevent any complete failures.
  • Store keys properly. It’s best to avoid extreme temperatures. For example, extreme cold can drain key fob batteries.
  • Have a spare key and know where it is. Make sure all drivers in the household are aware of its location.
  • Use a faraday pouch. Avoid your keys being relayed or broken while at home by storing them in a faraday pouch. It can help with blocking signals emitted from the keys.
  • Have a backup plan. Consider keyless entry options or storing a spare key with a trusted person.
  • Use key tracking devices. Tracking devices can help locate misplaced keys quickly.
  • Have breakdown cover in place. Check to make sure your breakdown cover includes help with lost or broken keys as standard.

Nobody wants to be left stranded due to something as small as a misplaced or malfunctioning car key. So follow the steps above, plan ahead, and look after your keys (to help look after your wallet).
