If the key fob hasn't been exposed to water, but still does not work it could be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan can assist in these situations.

Water Damage

There could be water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the board completely dry before putting in batteries.

If the key fob is not functioning after exposure to water, it could be possible to fix the issue by cleaning the chip using isopropyl alcohol or electronic cleaner.

Faulty 12 Volt Battery

A damaged battery could cause the key fob to work. When this happens, the car's computer system won't recognize that the fiat 500 remote key replacement is inside the vehicle.

Before you replace the battery, test it with the voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly then it's time to replace the battery.

Put an electrical load for a short time on the battery to determine its capacity. This will take off approximately 1% of the surface charge. Then measure the voltage again. The higher the capacity of the battery and the longer it can maintain its voltage. Ideal is that it stays close to 12 volts over several minutes.

Problems with Radio Signal

This is the most typical reason for the key fob not sending signals to a car. The battery could be replaced to fix this problem. But, it is essential to choose a battery that has the same voltage and size as the original.

Fobs are not indestructible and can withstand a lot. Contacts and buttons on batteries can be damaged through rough handling.

If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition the fuse could have blown. This is the most common reason for a scan tool to fail. The simple fix is usually to replace the fuse that is blowing up.
