Dead Coin Battery

The battery in the key fob is held in place by metal retaining clips. If the clips aren't secure, they can cause problems with contact, which can prevent your remote from receiving power. Make use of a flathead screwdriver to open the retaining clips and remove the old battery. Make sure that the battery you choose to use has the same size, voltage and specification as the original.

The exposure to water can cause the key fob to corrode or be damaged. Even a brief bath in soapy, warm water can cause damage to the chip. It's best to keep your key fob in a dry environment.

Water Damage

If your key fob isn't working correctly, it could be caused by water damage. Key fobs have rubber seals that protect them from being damaged by rain or splashes of water, but it is vital to keep your keys from being tossed into the pool, ocean and washing machine!

Faulty Chip

Faulty Receiver Module

Fiat key fobs send a 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 a few things that can cause the fob to stop working. This could be due to a dead battery, water damage, worn out buttons, a receiver issue, signal interference or an issue with the chip.

If the fob has been stored in a place that has suffered a severe trauma, such as being dropped on hard floor or getting washed in a wash machine the fob may not be capable of communicating with the car's Body Control Module (BCM). This is because the BCM is secured and will only accept signals from a genuine key, and not from any other.
