Diagnostics of a fault

The key fob has an electronic chip which communicates with your Fiat's immobiliser system to ensure that only authorized vehicles are able to start engines. If the transponder in your key fob is damaged, it will not be connected to the immobiliser. This means that your vehicle won't start.

The good part is that it's attainable to fix a damaged key fob if the chip isn't physically damaged. A professional locksmith will employ standard techniques used by dealers to repair it quickly.

With an OBD scanner, it is possible to verify if the fob is still communicating with the receiver module. It's a simple process and provides an initial indication of where the issue is. If the OBD scanner indicates that there is no communication between the receiver and transmitter modules, it may be necessary for the fob's transmitting module to be replaced. This could be a costly option, and should be left to an expert locksmith.

Dead Coin Battery

A dead coin battery is the most common reason for a key fob to not work. This is an easy fix that only takes a few minutes. First, make sure that the key fob is within range of your vehicle. Then, press the "Lock" or "Unlock" button to test if it responds.

If the key fob's signal is out of range, it might not respond at all or might only work intermittently. This could also be a sign that the circuit board inside the key fob has gone bad. In this scenario you'll need to check the manual of your owner for instructions on how to reprogram the key fob.

The mechanical latch can be removed from the back of the key fob. (See the image below). Then, gently pry the edge of battery holder away from the switch to take out the old battery. Then, put a new #3 volt battery into the fob assembly, with the "+" side facing towards the cover on the rear of the key fob, and the "-" side facing down towards the rubber buttons.

Water Damage

The key fob isn't waterproof even though it is fitted with rubber seals that prevent water from getting inside the electronic chip. A splash of rain or a wash cycle is likely to be acceptable, but submerging the key fob in ocean or pool water is likely to cause damage.

If the key fob is exposed to water and stops functioning, it will need to be reset. This can be done using the instructions found in the owner's manual or by bringing it to a professional auto locksmith or an Fiat dealer.

Another reason that a fob may stop working is that it's out of the range of your car. Key fobs generally have a range of around 30 feet, and if they're too far from your car, they won't recognize them. The first step is to get closer to your vehicle. If it doesn't work, the key fob battery might need to be replaced. You can find battery replacement instructions for most automobiles on YouTube or in the owner's manual. If your key fob appears rough and scratched, it's time to replace it.

The cars are equipped with a remote control which sends a wireless message to the car in order to switch the engine on and off. A locksmith can repair the damaged key fob.

Keys that are unpaired

When these become worn or loose, it could cause contact problems and no power. Replace the battery by purchasing a new one of the same voltage, size and specifications, or a spare.

It is essential to dry out the key fob if it was submerged in liquid. This can be done with isopropyl or an electronic cleaner. It is also recommended to take the battery off and clean the circuit board prior to replacing it.
