This provides an additional layer of security, decreasing the risk of thefts and other vehicle-related crimes.

It's therefore important to keep the key fob and keychain as far away from water as possible.
It's also important to remember that a transponder is specifically programmed to a specific vehicle, and changing any part that is sensitive can result in issues with compatibility that could impact its functionality.
