Bypassing a Car Transponder Key

There is a large variety of reasons you might need to bypass the transponder functionality of common car keys. Say you dropped your keys in water and the transponder functionality doesn’t work anymore, or maybe you’ve lost your keys and don’t have the time to go get a new key because you need to be somewhere right away, and you grew up in a rough neighborhood so you happen to know how to hot wire a car, but I mean you’d never use it on anyone’s car but your own, and – well, anyway, you need to bypass the transponder.

This will allow the ignition system to talk to the transponder despite the transponder being attached to a different key, enabling your car to start.

There are a variety of ways on the internet advertising means of bypassing transponder keys. We recommend not trying these! They can leave you with a completely unresponsive car security system, preventing your car from starting entirely.

It sucks, but that’s life.
