It's A Fiat 500 Keys Success Story You'll Never Be Able To

fiat doblo key fob replacement Panda Key Fob Replacement

fiat key fob not working Panda keyfobs are equipped with a transponder that transmits an electronic signal from the fob to the car to open doors or start the motor. The fob may stop working for a variety of reasons.

A dead battery for the coin is the most frequent cause of a spare key fiat 500 fob malfunction. Other causes are water damage or a malfunctioning module and interference signals.

Dead Coin Battery

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

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned prior to being used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will be the solution.

If the key fob hasn't been exposed to water, but it is still not working it could be due to a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan can help in these instances.

Water Damage

You could have water damage if your fiat punto key fob replacement fob was submerged in a puddle, pool or washing machine. It is usually possible to be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It is a good idea to allow the fob to dry completely prior to installing a new battery.

If your key fob has stopped working, even after replacing the battery and changing the program, you could have a problem with the receiver module. You can find reprogramming instructions for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the vehicle's system. If the chip is damaged, it will no longer transmit and receive signals to the vehicle. This could be due to dropping the key fob, or due to exposure to water. If the key fob stops working after exposure to water it is possible to repair it by cleaning the chip with isopropyl alcohol or electronic cleaner.

If the fiat 500 abarth key fob continues to not respond even after cleaning it it is likely that the component is damaged and must be replaced. A defective receiver can cause the key to cease to function. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in your key fob is a vital component of the anti-theft system in your vehicle. It sends a signal the immobiliser device in your vehicle to tell it whether or not the key is legitimate. If the chip is damaged or broken, the car won't start.

A malfunctioning chip could be caused by interference signals from other objects or weather conditions that are bad, or transmitters operating on the same frequency near your vehicle. In this scenario an upgrade to the fob will be required.

Contacts of the battery may be damaged.

The battery contacts in the key fob are delicate and could be damaged by repeated use. If they are broken or bent, the fob will not transmit any signals to the receiver modules in the car.

Modern fobs come with rubber seals that keep out water. Submerging them in water even if just small splash or drizzle could damage the chip's electronic circuit.

The key fob houses a chip that communicates with the vehicle's immobilizer to allow it to start it. This system uses crypto coding systems in vehicles that are more modern, or the old red key system in older models. If the chip is damaged it will have to be replaced.

A faulty 12 Volt battery

A faulty battery may cause the fiat punto key replacement fob to work. When this happens, the car's computer system will not be able to recognize that the remote is inside the vehicle.

Before replacing the battery, test it using a the voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly then it's time to replace it.

To test the battery's power, place an electrical load on it for a few minutes. This will eliminate approximately 1 percent of the surface charge. After that, measure the voltage. The higher the capacity of the battery is, the longer it will keep its voltage. It is ideal to maintain close to 12 volts over several minutes.

Problems with Radio Signal

This is the most frequent cause of a key fob that ceases to send signals to the car. The issue can be fixed by replacing the battery. It is essential to purchase an identical battery voltage and dimensions as the original.

Fobs aren't indestructible and can be damaged by a lot. Contacts and buttons on batteries can be damaged by rough handling.

The signal could also be disrupted by other transmitters or objects that use the same frequency. For instance, a lighting control panel close to your home can transmit interference using the same bandwidth that key fobs use. This can affect the remote control of your car.

Incorrect OBDII scan tool

There are many reasons scanner tools may not function. Certain are more complicated than others.

Professional scan tools let mechanics to observe the car's networks and run various self-tests. These tools can save a lot of time, but are expensive and not accessible to most DIYers.

If your OBD2 scanner doesn't work, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's likely that a fuse has blown. This is the most frequent cause of scan tool failure. The easiest solution is to replace the blown fuse.
