Dead Coin Battery

A dead battery is the most common cause of your Fiat 500 keyfob not locking or unlocking the doors. The key fob contains a coin cell battery that will drain quickly in the event that it is not used often enough. If your remote has started to show signs of a loss of range, or has stopped working and the battery is not working, it could be dead.

The battery in the key fob is secured by metal retaining clips. If the clips aren't secure, it can cause contact issues which will prevent the remote from receiving power. Using a small flathead screwdriver, break the retaining clip open to remove the current battery and replace it with a new one. Make sure that the battery you choose to use has the same voltage, size, and specifications as the original.

The key fob might be damaged or corroded by water exposure. Even a small shower in soapy water can harm the electronic chip within. Keep your key fob dry.

Water Damage

Water damage could be the reason behind your key fob not functioning properly. The rubber seals on key fobs protect them from being damaged by a small splash or drizzle of water. However, it is essential to keep the car keys away from the washing machine, the ocean, and pool.

The key fob has an electronic chip in it that sends a signal car's immobilizer system. The chip is what allows the 500 to start and lock. If it gets wet, however it will not function.

You can clean the inside electronics of your keyfob with isopropyl Alcohol or an electronic cleaner to see whether they're still working. It is best to replace a key fob in the event that it's submerged into salt water rather than attempting to repair it yourself.

While a replacement fob could cost a bit of money, it's a lot cheaper than having to pay for your Fiat 500 to be towed to a dealership and fixed! You could also do it yourself by following just a few steps. Be sure to use the right battery type before you attempt to open your key fob. You can find step-bystep directions for any car keyfob online.

Faulty Chip

The chip inside the key fob communicates with the car's immobiliser unit to make sure the vehicle is only capable of starting when the correct key is inserted. If the chip is damaged or destroyed the car will not start regardless of what you do.

A chip that is damaged can happen due to several reasons, but the most common cause is water damage or the battery being dead. Regardless of the reason, it's recommended to delegate the job to a locksmith, as they will be able to replace the chip fast and at a reasonable cost.

If your key fob does not function after being exposed to clean water from a tap or rain take the battery off. Wipe down the electronic component with an old towel. If the key fob does not work, there's a chance that it has a fried component and needs to be replaced.

Faulty Receiver Module

Fiat key fobs transmit an electronic signal to the vehicle which will unlock and lock doors (and start the vehicle for those with an automatic transmission) up to 50 feet. However, there are several things that could cause the fob to stop functioning. This includes a dead coin-battery or water damage, worn-out buttons an issue with the receiver, signal interference, or a malfunctioning chip.

If the fob is in a pocket which has been subject to extreme trauma, like being dropped on a hard floor or being washed in a washer and it isn't capable of communicating with the car's Body Control Module (BCM). The BCM is a security device which will only accept signals from genuine keys.

You'll need to replace the fob in case this happens. A professional locksmith will manage the entire process of replacing keys including programming a new key to your 500. They can even offer a clone fob that works exactly like the original (and costs just less than what it would cost).
