Why We Love Fiat 500 Keys (And You Should Too!)

fiat doblo key fob programming Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip that sends the signal to your vehicle to open the doors and start the engine. The fob may stop working for a variety.

The most frequent cause of fiat key fob not working fob failure is a dead coin battery. Other causes include water damage, malfunctioning receiver modules and signal interference.

Dead Coin Battery

If your key fob battery has died, the first step is to replace it. Use a new button cell battery that is the same size, voltage, and specification as the old one.

If the key fob has been exposed to water, for example a splash of rain or salt water at the beach, it will need to be cleaned before it is able to be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will help.

If the key fob doesn't working despite not being exposed water, it could be due a malfunction in the receiver module or internal electronic chip. In these instances it is possible that reprogramming the key fiat fob with an OBDII scanner may aid.

Water Damage

If your key fob has taken submerged in a pool or puddle or gone through the washing machine, you may have some water damage. You can usually get it working again by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is a good idea to let the fob dry completely before putting in a brand new battery.

If your fiat doblo key fob programming fob stopped working, even after replacing the battery and changing the program, you could have a malfunctioning receiver module. Reprogramming instructions are available for most remote key fobs on YouTube or in the owner's guide. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains the chip that communicates with the car's system. If the chip is damaged, it cannot longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or by exposure to water. If your key fob isn't functioning due to water exposure or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob is still unable to not respond even after cleaning it it is likely that the receiver module is not functioning properly and needs to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in the key fob is an essential component of the anti-theft systems in your vehicle. It sends a signal to the immobiliser unit in your car to determine whether or not the key is valid. The car won't start in the event that the chip is damaged.

A defective chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this instance an upgrade to the fob will be needed.

Faulty battery contacts

The battery contacts inside the key fob are delicate and may be damaged by repeated use. If they are damaged or bent, the key fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals in order to keep out water. A splash of water or light rain should be fine However, submerging them in salt water could cause damage to the chip's electronic components.

The key fob comes with a chip which communicates with the immobilizer system of the vehicle to begin it. The system is based on the old red keys in older vehicles or the cryptocoding system that is used in modern vehicles. This chip needs to be replaced if it's malfunctioning.

Problematic 12 Volt Battery

A defective battery can cause the key fob to cease to function. The lost car key fiat's computer will not recognize the remote if this occurs.

Before you replace the battery, test it by using a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it's time to change it.

Set an electrical load for a few seconds on the battery to determine its capacity. This will remove about 1% of the charge on the surface. Then, you can measure the voltage. The higher the capacity of the battery, the longer it can keep its voltage. Ideal is that it stays close to 12 volts for several minutes.

Faulty Radio Signal

This is the most common reason for a key fob to stop sending signals to the car. This problem can be solved by replacing the battery. It is crucial to buy a battery that has the same voltage and dimensions as the original.

Fobs take a lot of punishment, and aren't impervious to destruction. The battery contacts and buttons could be damaged by rough handling.

Other transmitters or objects that use the same frequency may also interfere with a signal. For example, a light-control panel that is near your home could transmit interference on the same frequency as key fobs utilize. This can interfere with the remote control of your car.

Faulty OBDII Scan Tool

There are a number of reasons why a scan tool may not work. Some are more complex than others.

Professional scan tools allow a mechanic to observe the car's networks and run a range of self-tests. These can be real time savers but they are also extremely expensive and are out of the budget of most DIYers.

If your OBD2 scanner isn't turning on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape it's possible that a fuse has been blown. This is the most common reason for failure of the scan tool. The most straightforward fix is to replace the fuse that has been blown.
