Methods of Diagnoses

Without properly diagnosing the reasons for a car key fob not working, you can end up spending time and money on things that will not fix the problem. The ways to handle the troubleshooting can essentially be broken up into two categories: what to do when you have a spare key fob and what to do when you do not have a spare key fob.

1. Replace Batteries

With a key fob not working, the easiest and cheapest solution is to change the batteries. This may not solve the issue, but it is worth trying a troubleshooting measure. Dead batteries are the most common reasons for a car key fob not working.

2. Reprogramming

Older vehicles have DIY programming procedures for their remotes, but almost all keyless ignition fobs will require advanced equipment. The more complex the remote, the higher the cost to program a car key. With a key fob not working, you may run into problems programming or even reprogramming your existing fob due to modern security measures.

3. New Key

In the worst-case scenario, a key fob not working will require a full replacement. The cost of replacing a car key fob will vary based on the make, model, and year of the vehicle. You can lower your replacement costs by purchasing aftermarket electronic car keys instead of the official branded products.

4. Fix The Car

When the issue is with the car itself, the issue is not a key fob not working. Your solution will vary depending on what the car key fob is not doing.

Calling A Locksmith

In almost every case of a car key fob not working, a locksmith will be your best option for finding a fix. Unlike a mechanic, who will require your car to be towed to their shop, a locksmith can come directly to you.
