Fiat 500 Replacement Key Fob

It's possible to replace the battery if your 500 remote key fob isn't working. However, if you replace the battery and it is still not working, then the problem may be elsewhere.

Dead Coin Battery

The most frequent reason that your Fiat 500 key fob will not lock or unlock the doors is a dead battery. The battery for the coin cell in the key fob is likely to drain quickly if you don't use it often enough. If your remote began to show signs of weakening such as a loss of range and then completely stopped working it is likely that the battery is dead.

The battery in the key fob is held in place by steel clips for retaining. If the clips aren't tight enough, it can cause contact issues, which could prevent your remote from receiving power. Make use of a flathead screwdriver to break open the retaining clip and then remove the old battery. Be sure to choose a replacement battery with the same kind of voltage, the same size, and specification as the original battery.

The key fob could also be damaged or corroded due to exposure to water. Even a short bath in soapy water can harm the electronic chip within. Keep your key fob dry.

Water Damage

If your key fob isn't operating properly, it could be due to water damage. Key fobs are fitted with rubber seals that prevent them from being damaged by rain or splashes of water, but it is crucial to keep your keys safe from the pool, ocean and the washing machine!

The key fob has an electronic chip that transmits an alert to the immobilizer system of your vehicle. The chip allows the 500 to be locked and started. If it gets wet, however it will cease to work.

Try cleaning the internal electronics of your key fob with isopropyl Alcohol or an electronic cleaner to see whether they're still working. It is recommended to replace the key fob if it's submerged in salt water rather than try to fix it yourself.

While a replacement fob might cost you a bit of money, it is far less expensive than having to pay for your fiat keys 500 to be towed to the dealer for repair! You can also make it yourself with just a few steps. Be sure to have the correct battery type before you attempt to open your key fob. This task is much simpler than it appears, and you can find step-bystep instructions online for almost any key fob in your car.

Faulty Chip

The chip inside the key fob connects directly with the immobiliser of your car to ensure that the vehicle will only start when proper keys are inserted. If the chip is damaged or corrupted the car won't start regardless of what you do.

Damage to the water or a dead phone battery are the most frequent causes of an unreliable chip. Regardless of the reason, it's recommended to delegate this work to a locksmith as they will be able to repair the chip for you swiftly and at a cost-effective price.

If your key fob fails to function after exposure to clean water from the tap or rain, remove the battery and wipe down the electronic component with a towel to ensure that it is completely dry before putting it back in. If the key fob still doesn't work it's most likely to be a damaged chip that must be replaced.

Some people will turn to their dealer when in need of an entirely new fiat 500 spare key key fob, but this is a expensive option. United Locksmith is the best place to go if you need your Fiat keyfob fixed at a reasonable cost. We have the tools and experience needed to repair your Fiat key fob in a quick and professional way.

Faulty Receiver Module

Fiat key fobs send an electronic signal to the vehicle that will unlock and close doors (and start the vehicle for those with an automatic transmission) up to 50 feet. However, there are some things that could cause the fob to cease functioning. This includes a dead coin battery, water damage, worn buttons, a receiver module issue or signal interference, or an electronic chip that is malfunctioning.

If the fob is stored in a place that has been subject to extreme trauma, like being dropped on hard floor or being washed in a washer and it isn't able to communicate with the car's Body Control Module (BCM). The BCM is a security system that will only accept signals from genuine original keys.

If this is the case, you have to replace your fob. A professional locksmith will take care of the entire process of replacing keys including programming a new one for your 500. They can even provide you with the fob cloned to work exactly like the original (and costs just less than what it would cost).
