Dead Coin Battery

The most common reason your Fiat 500 key for fiat 500 fob will not unlock or lock the doors is due to a dead battery. The key fob has a coin cell battery which will quickly drain if it is not utilized frequently enough. If your remote started to show signs of weakness such as a loss in range or stopped working completely, the battery is probably dead.

Metal clips hold the battery in inside the key fob. If the clips aren't tight enough, it could lead to contact issues which will prevent your remote from receiving power. By using a small flathead screwdriver, pull the retaining clip to remove the current battery, and replace it with a brand new one. Choose a battery that is the same size, voltage and specifications as the original.

The key fob can also be damaged or corroded through exposure to water. Even a short bath in soapy water can harm the electronic chip within. Make sure your key fob is dry.

Water Damage

Water damage may be the reason behind your key fob's inability to function properly. The rubber seals on key fobs prevent them from getting damaged by a tiny splash or drizzle of water. However, it is essential to keep the keys from the washing machine, the ocean, and pool.

The key fob comes with an electronic chip that sends a message to the immobilizer system in your car. This is the reason why your 500 can start or lock, however when the chip becomes wet, it can no longer work.

Try cleaning your key fob's internal electronics using isopropyl alcohol, or an electronic cleaner to determine whether they're still in good condition. However, it's recommended to purchase a replacement from a dealership instead of trying to fix the key fob that is submerged in salt water.

While a replacement fob could cost you a bit of money, it's much cheaper than having to pay for your Fiat 500 to be towed to the dealership and repaired! You can also do it yourself in several easy steps. Make sure you have the correct type of battery before attempting to open your key fob. There are step-by-step directions for any key fob in your car online.

Faulty Chip

The chip inside the key fob communicates with your vehicle's immobiliser to ensure that the vehicle is able to start when the correct key is used. If the chip is damaged or corrupted in any way, your car will not start.

Damage to the water or a dead cell phone battery are the most common reasons for defective chips. It is best to hand over the task to a professional locksmith who can repair the chip quickly and at a reasonable price.

If your key fob does not function after exposure to water that is clean from the tap or rain take it off the battery. Wipe down the electronic component with an old towel. If the key fob isn't working it's most likely a fried chip and will require replacement.

Faulty Receiver Module

Fiat key fobs transmit an electronic signal to the vehicle that will unlock and lock doors (and start the car if it has an automatic transmission) up to 50 feet. However there are a few things that could cause the fob to cease working. This includes a dead coin battery damaged by water or worn buttons and a receiver module issue and programmer signal interference, or a malfunctioning electronic chip.

If the fob was in a pocket which has suffered severe trauma (such as being dropped onto a hard floor or being washed in the washer) it might not be able to connect with the Body Control Module (BCM) of the vehicle. The BCM is a security system that will only accept signals from genuine original keys.

You'll need to replace the fob in case this occurs. A professional locksmith can take care of all aspects of the replacement process as well as programming a new one for your 500. In fact, they could provide you with a replica key that works just like your original fob (and costs less than the cost).
