Trying to find a replacement or fix for a car transponder key can be stressful and
time-consuming. And if research hasn’t been done properly, it can result in a costly repair or
replacement, something we want to help you avoid.

What is a Transponder Key?
Most modern cars now use a transponder key as they add extra security, making it difficult for
thieves to steal your vehicle. When pressing the button on your transponder key, a low
frequency signal is transmitted via a microchip to a remote receiver in your car that tells it to
unlock.
As well as extra security, another benefit of transponder keys is that you won’t find yourself
locked out of your vehicle - the signal would automatically unlock it. Car lock outs can be
particularly dangerous if children or pets are involved, in which case you need assistance as
soon as possible.
Where can I fix or replace my Transponder Key?
Unfortunately, transponder keys tend to be more expensive and tricky to replace or repair than
your standard car key. Your best option is to contact an auto locksmith who has the correct
equipment to hand. Car dealerships are an alternative option, however they tend to charge a lot
more and aren’t as quick - and nobody wants to be without their vehicle for longer than they
need to be, right?
As we always say, make sure you have a spare to hand to avoid unnecessary stress or panic in
situations where you’ve lost, broken or had your car key stolen.
