Why does my car key sometimes work and sometimes not?

You're about to drive home, press your car key and nothing happens. Moments later, it suddenly does work again. Super frustrating! But you're not the only one: this happens more often than you think. In this blog we explain what causes it and what you can do about it.


1. Low battery
The most common cause is an empty or weak battery. Often your key will still work just once in a while, but the range will get worse or it will falter.

Tip: Replace the battery of your car key on time. View our Batteries for your model here.


2. Malfunctioning due to environmental factors
In some parking garages or near supermarkets, you may experience signal interference. Transmitters, antennas or even other car keys can cause interference that temporarily prevents your key from working.

Try a different spot or get out of the car and hold the key closer to the dashboard.


3. Damaged circuit board or buttons
If your key sometimes works and sometimes doesn't, there may also be something broken inside. Think of the circuit board, solder joints or the buttons themselves.

In this case, you can have your key checked and repaired through our service for Repair car keys


4. Key is (almost) not properly coded anymore
In modern cars there is a chip (transponder) in the key. If this no longer communicates properly with the car, the key will not work properly. Sometimes this is due to damage, sometimes because the key needs recoding.

No longer a working key? Then quickly get a Car key refill through our experts.
