What to do if your car key overheats in the sun

Especially in the summer months, your car key can get quite hot if it's left in full sun for long periods of time. Whether it's on the dashboard, on a beach towel or in a hot car: heat can cause problems. In this blog, you'll find out what you can do if your key overheats, the risks involved and how to prevent damage.

What happens when keys overheat?
Car keys contain fragile electronics. Prolonged exposure to heat can melt parts, loosen contacts or drain batteries. In some cases, your key may temporarily stop working or even stop working altogether.

1. Let the key cool down well first
If you notice that your key feels hot or stops working after exposure to the sun, put it in a cool, dry place. Avoid direct use or cold shock (such as putting it in the refrigerator), as this can cause additional damage.

2. Check if the battery is still working
An overheated battery can drain faster. If your key stops working properly, replace the battery.

3. Replace damaged parts
Is the plastic of the key housing deformed or cracked? Then it is wise to replace it. You can easily order a new key housing from us or have a complete new car key made.
