Reasons Your fiat car keys 500 Key Fob Won't Work

A key fob for the fiat 500 key 500 is a handy way to unlock the doors and start the car. There are many reasons the fob could stop working. This could be due to a dead battery, water damage, issues with the receiver module, and interference.

This listing is for a NEW replacement key for fiat 500 Fiat Panda Key Fob Replacement Flip Key Remote - an exact replica of the Ilco brand that must be professionally programmed by a local automotive locksmith (click here for Locksmith Search). It comes with trunk, lock and unlock buttons.

Dead Coin Battery

A dead battery is the most common cause of your 500 key fob not working. Modern key fobs only have only a limited range of operation and must be within a few inches of your vehicle in order to function. If you are far from your car and hit the keyfob, it won't respond and display the message "Key Fob Not Detected".

If this happens, replace the battery of your coin cell (Part number CR2032) by a new one from a reputable brand such as Panasonic, Duracell, or Energizer. You can find them at the local hardware store or online.

You can test the battery of your coin-cell by pressing the buttons while standing close to your fiat ducato key 500. The parking lights should light up and the key fob should operate the lock and unlock switch.

If the key fob won't work after replacing the battery, it could be damaged by water, which prevents it from communicating with the receiver module in your car. Water damage can occur in a number of ways, ranging from small splashes to submerging your fob in salt water at the beach. If you suspect that your fob was exposed to water, place it in a bag of rice to draw out the moisture. If that doesn't work, your fob may need to be reset by a professional auto locksmith or by the dealer.

Water Damage

Damage to the water supply can occur if you submerge the fob in the ocean or wash it in a machine. Saltwater can cause the circuit board to become shorted and eventually end up dying. It's not a good idea to submerge the fob in water however, don't give it up when you accidentally drop it in water or fail to remove it from your pocket.

Receiver Module Issues

One of the most common reasons your 500 key fob may stop working is because it's out of range. The remote usually has an operating range of 30 feet or less and if it's far from your vehicle, it won't respond to your commands. It's easy to remedy this by moving your remote closer to your vehicle until it responds.

If the key fob failed to work one day without notice and you've tried every option at home to solve it e.g. replacing the battery, reprogramming it and using the spare key fob, you might have a malfunctioning receiver module on your 500. The receiver module is located under the dash and receives the radio frequency signals from the key fob. It converts them to electronic commands that the vehicle interprets.
