Dead Coin Battery

The most frequent reason that the 500 key fob won't work is an inactive battery. Modern key fobs have a very limited range of operation, and should be within just a few feet of the vehicle to function. If you're far from your vehicle and you press the key fob button the car won't respond and will display an "Key Fob Not Detected" message in the instrument cluster.

If this happens then replace the battery for your coin-cell (Part Number CR2032) by a fresh one of a reliable brand, like Panasonic Duracell or Energizer. You can find them in the local hardware store or on the internet.

You can test the coin-cell battery by pressing the buttons while you're standing close to your fiat Panda key 500. The lost car keys fiat will blink its parking lights, and the key fob will operate the lock and unlock switches.

If the key fob doesn't function after replacing the battery, it may have water damage that prevents it from connecting to the receiver module in your vehicle.

Water Damage

Remove the battery first. Clean the electronic chip using isopropyl alcohol or a similar product and then dry it thoroughly before replacing the battery. Then check the fob to test if it works.

Interference

In addition to a dead coin battery, the key fob may not be able to transmit or receive the signal due to interference.

If the key fob has stopped working one day without notice, or after trying every option at home to resolve it e.g. replacing the battery, reprogramming it and using the spare key fob, it could have a defective receiver module on your 500.
