Reasons Your fiat replacement key 500 Key Fob Won't Work

This listing is for an NEW replacement fiat ducato key fob Flip Key Remote - an exact replica of the Ilco brand that must be programmed professionally by a local locksmith (click here to search for a Locksmith Search). Includes trunk, lock and unlock buttons.

Dead Coin Battery

The most frequent reason why your 500 key fob will not function is an inactive battery. Modern key fobs offer a limited range of operation and must be within only a few inches from the vehicle to function. If you are far from your vehicle, and you hit the keyfob, it will not respond, and display the message "Key Fob Not Detected".

If this happens, simply replace the battery in the coin cell (Part number CR2032) by a new one from a reputable manufacturer like Panasonic, Duracell, or Energizer. They are available at your 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 car keys 500. The parking lights will flash and the key fob will operate the lock and unlock switches.

If the fob's fiat ducato remote key programming doesn't work after replacing the battery, it might have water damage that prevents it from connecting to the receiver module in your vehicle. Water damage can occur in a variety of ways, such as a simple splash or submerging your key fob in saltwater at the beach. If you suspect your fob has been exposed to water, put it in a dry rice bag to pull the moisture out. If this isn't working, you'll have to get your fob reprogrammed either by an auto locksmith or dealer.

Water Damage

Water damage can occur if you immerse the fob in the ocean or wash it in a machine. Saltwater is particularly dangerous to the circuit board of the fob which causes it to short out and eventually die. It's not a good idea to submerge the fob in water however, but don't give it up if you accidentally drop it in water, or fail to remove it from your pocket.

First, remove the battery. Clean the electronic chip with isopropyl ethanol or a similar product and dry it thoroughly before replacing the battery. Check the fob again to check if it's working. If the fob doesn't work, it might need to be reset. This is usually handled by an auto locksmith or dealer.

If the key is older and was not programmed to your vehicle it is likely to need to be replaced completely. A professional automotive locksmith can carry out this simple task. The locksmith will need to cut the key to match the ignition of your car. They'll also need to reprogram the fob for the system of your car. This is a quick and cost-effective procedure that is usually completed in the same day.

Receiver Module Issues

One of the most common reasons why your 500 key fob could stop functioning is because it's out of range. The remote's range is of 30 feet, which means if you are too far away from your vehicle it will not respond to your commands. You can easily remedy this by moving your remote closer to your car until it responds.

If you've replaced the battery in your coin (commonly known as a "button" or "watch") and the fob isn't working It could be because of an internal circuit board issue. Reprogramming the fob is usually the solution to the issue. There are instructions on how to do this on the majority of vehicles by searching YouTube or looking through the owner's manual.

You may need to replace the metal retaining clips that hold the battery of your coin in place. If they lose tension, it could prevent your coin battery from being properly seated and cause your remote to malfunction.

In rare instances it is possible that the fob will become disconnected from your vehicle because of software or hardware issues. This can cause a major trouble, but you could often fix this by visiting a local dealer or auto locksmith to reprogram your fob for you. In some cases it may be necessary to reinstall the program in your body control module, as well.

Interference

In addition to a dead battery on a coin, the key fob may not be able to receive or transmit the signal due to interference. This could occur if the key fob is in proximity to radio transmitters (cell phones, radar detectors) or another source of electromagnetic radiation. Other reasons the key fob might not work include a weak connection to the buttons or the internal chip, or water damage.

If the key fob has stopped working one day in the middle of the night and you've tried everything you can do at home to solve it e.g. battery replacement, reprogramming and using the spare key fob, you could have a damaged receiver module on your 500. The receiver module, located beneath the dashboard, is able to pick up radio frequency signals from your key fob. It converts the signals into electronic commands that are then interpreted by the vehicle.

There is a simple way to reset the lost fiat 500 key's in-board system, including the keyfob. Disconnect the battery for 15 minutes by taking off first the negative cable, then the positive cable. Then reconnect the battery. This will get rid of any remaining electrical charge and restart the car's computer system, which could help get your key fob working again. If the problem persists you should consult an expert technician. They will be able to determine the exact cause of problems.
