cylinder makes it simple to open doors and start your vehicle. However, there are a variety of reasons why the fob won't be functioning. These include a dead battery, damaged receiver module, water damage issues, and interfering.
This listing is for an NEW replacement Fiat Flip Key Remote - similar to the Ilco brand that must be programmed professionally by a local locksmith (click here for 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 come with a limited range of operation, and should be within some feet of the car to operate. If you're far from your car and press the keyfob button it will not respond, and display the message "Key Fob Not Detected".
If this happens, replace the battery of your coin cell (Part number CR2032) with a brand new one from a reputable manufacturer such as Panasonic, Duracell, or Energizer. You can usually find them at your local hardware store or on the internet.
After you've replaced the coin cell battery It is possible to test it by standing near your Fiat 500 and pressing the buttons. The car will blink its parking lights, and the key fob should work the lock and unlock buttons.
If your key fob isn't working after replacing the battery, it may be water damage which hinders it from interacting with the module in your vehicle. Water damage can happen through a variety of methods, including a simple splash or submerging your key fob in saltwater at the beach. If you suspect your fob has been exposed to water, you can try placing it in a dry rice bag to draw the moisture back out. If this isn't working, you'll have to get your fob replaced by an auto locksmith or a dealer.
Water Damage
The fob does have rubber seals to keep water from the electronic chip inside and out of the ocean or washing it in a machine can cause water damage. Saltwater poses a particular risk to the fob's circuit board and can cause it to short out and eventually die. In the event that you let your fob get wet, it's not an ideal choice however, if you drop it into a glass of water or fail to remove it from your pants pocket prior to running the washing machine, don't give up hope.
Take the battery off first. Clean the electronic chip using isopropyl alcohol or another similar product and then dry it completely before replacing the battery. Check the fob again to check if it's functioning. If the key doesn't function, it may have to be changed. This is usually handled by an auto locksmith or dealer.
If the key is older and has not been programmed to your car It will most likely need to be replaced completely. This is an easy process that can be completed by a professional automotive locksmith. The locksmith will require the key cut to match the car's ignition. The locksmith will also have to reprogram your fob into the car's system. This is a fast and inexpensive process which can be completed the same day.
Receiver Module Issues
One of the simplest reasons your 500 key fob won't be functioning is because it's out of range. The remote typically has an area of 30 feet or less and if it's far from your car, it will not respond to your commands. This can be fixed by moving it closer to your vehicle until it starts responding.
If your fob won't work after you replace the coin battery, also called a "button", "watch" or "button" it could be due to an issue with the circuit board inside. Reprogramming the fob is usually the solution to this issue. You can find the instructions for most vehicles on YouTube or in the owner's guide.
It is possible to replace the metal retaining clips that hold the battery of your coin in place. If they become loose, it can prevent your coin battery from being properly seated, causing your remote to malfunction.
In rare cases the fob might become desync'd with your vehicle because of software or hardware issues. This could cause a significant headache, but you can usually fix it by visiting an auto locksmith to have them reprogram your fob for you. In some instances they may have to install the software again in your body control module too.
Interference
Interference can also cause the key fob to not be able to receive or transmit a signal. This can happen when the key fob is located near a radio transmitter (cell phones or radar detectors) or any other source of electromagnetic radiation. The key fob could not work because of a problem to the buttons, water damage or damage to the internal chips.
If the key fob has stopped working one day out of the blue or after trying everything you can do at home to solve it e.g. You may have a faulty 500 receiver module if you've tried replacing the battery, reprogramming, and using an alternative key fob. The receiver module is located under the dash, and it picks up the radio frequency signals from the key fob. It transforms the signals into electronic commands which are then translated by the vehicle.
Fortunately, there's an easy method to reset all of the onboard systems in your 500 keys, including the key fob. Disconnect the battery for 15 minutes by removing first the negative cable and then the positive cable. Reconnect the battery. This will remove any remaining electricity and restart the car's computers. This can help the key fob to function again. If the issue persists you should speak with an experienced technician. They will be able to determine the exact cause of any issues.
