There is no shortage of push-to-start cars today, and the key in your pocket plays a lot more roles than you may know, here is an explanation on how these keys operate, what may go wrong and the whole process of replacement, explained simply.
A proximity smart key communicates continuously with your vehicle using radio signals and when it is close enough, the car detects the key and allows the owner to unlock and start the car without a traditional metal key inserted in the ignition.
These keys generally have problems either running out of battery, losing synchronization, or being damaged by water and impacts. All these common problems can be found on our troubleshooting page for fobs.
Smart keys contain more electronic components, and require specialized configuration to match the car's security system. This is why they belong at the expensive end of the spectrum. They can still be cut and programmed on site by fob programming.
As they broadcast signals constantly, proximity keys may be exposed to relay attacks. Using a simple blocking pouch for keys can easily help prevent such attempts. You can find other solutions in our security guide.
Most dead fobs come down to a handful of simple causes. Work through them before assuming the worst.
