10 Meetups About Fiat 500 Keys You Should Attend

fiat keys replacement Panda Key Fob Replacement

fiat 500 key (online) Panda keyfobs are equipped with a transponder which transmits signals from the fob to the car to unlock doors or turn on the motor. However, the fob could stop working for several reasons.

A dead coin battery is the most frequent cause of malfunctioning keys. Other causes include water damage, an inoperative receiver module and signal interference.

Dead Coin Battery

If your key fob battery has gone out of service, the first step is to replace it. Make use of a new button battery with the same size, voltage and specification as the previous 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. The trick is to use an old towel soaked in isopropyl or electronic cleaner.

If the key fob hasn't been exposed to water but still does not work it could be because of a problem with the receiver module or an internal electronic chip. In these situations, reprogramming the key fob with an OBDII scanner might help.

Water Damage

If your key fob has gotten submerged in a puddle or pool, or taken a trip down the washing machine, it could have some water damage. It's possible to get it back in working order by taking out the batteries and cleaning the circuit board with ruby alcohol. It is recommended to let the board completely dry before putting in batteries.

You may have a faulty module in the event that your remote stops working after replacing the battery or replacing it with. There are instructions for reprograming the majority of remote keys on YouTube or consult the owner's manual. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob has an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. This can be caused by dropping the key fob or by exposure to water. If the key fob stopped working after exposure to water it may be possible to fix it by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob continues to not respond after cleaning it, it is likely that the module is faulty and will require to be replaced. A faulty receiver can also cause the key to cease to function. This usually happens due to electromagnetic interference.

A defective electronic chip

The electronic chip in the key fob is an important component of the anti-theft system in your vehicle. It sends a message to the immobiliser inside your car to tell it whether the key is legitimate. Your car will not start when the chip is damaged.

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

Contacts of the battery may be damaged.

The battery contacts of the key fob could be damaged due to heavy use. If they are broken or bent, the fob won't send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals that block out water. Immersing them in water, even if it is just a light drizzle or splash could damage the chip's electronic components.

The key fob is equipped with a chip that communicates with the vehicle's immobilizer system in order to begin it. The system is based on the old red keys that were used in older vehicles, or the cryptocoding system found in newer cars. If the chip is not working properly and needs to be replaced.

Problematic 12 Volt Battery

A damaged battery could cause the key fob to work. If this happens, the car's computer system won't recognize that the remote is in the vehicle.

Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading decreases significantly it's time to change it.

To test a battery's capacity, place an electrical load on it for a few minutes. This will eliminate 1percent of the surface charges. Then measure the voltage again. The better the battery's capacity and the longer it can maintain its voltage. Ideally, it should remain at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the main reason for a key fob that stops sending signals to the car. The battery is able to be replaced to resolve this issue. It is however important to buy a new battery that has the same voltage and size as the original.

Fobs can take a lot abuse, but they're not impervious to destruction. Battery contacts and buttons can be damaged by rough handling.

A signal can also be affected by other transmitters or objects who use the same frequency. A light-control panel at your home, for instance, may interfere with key fobs that use the same frequency. This could interfere with the remote control of your car.

Incorrect OBDII scan tool

There are many reasons why scanners don't function. Some are more complex than others.

Professional scan tools allow mechanics to observe the car's networks and run a variety of self-tests. These are great time savers, however they are also extremely expensive, out of the reach of most DIYers.

If your OBD2 scan tool fails to turn on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK it could be that a fuse has blown. This is the main cause of scan tool failure. It is usually simple to fix the issue by replacing the fuse that has blown.
