fiat 500 remote key programming Panda Key Fob Replacement

Fiat 500 Key Fob Not Working Panda key fobs contain a transponder chip which sends the signal to your vehicle to open the doors and start the engine. The fob may stop working due to a variety reasons.

A dead battery for the coin is the most frequent reason for key fob malfunctions. Other causes include water damage an inoperative receiver module and signal interference.

Dead Coin Battery

Replace the battery if your key fob has died. Choose a button battery with the same voltage, size and specifications as your 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 a paper towel that has been soaked in isopropyl or electronic cleaner.

If the key fob hasn't been exposed to water, but isn't working, there may be a problem with the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob using an OBDII scanner can help.

Water Damage

You might have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's possible to get it working by taking out the batteries and cleaning the circuit board using ruby alcohol. It is recommended to let the circuit board completely dry before putting in batteries.

If your key fob isn't working even after replacing the battery and reconfiguring it, you may have a problem with the receiver module. There are reprogramming guidelines for all vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is the chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob could cause this, as could water exposure. If the key fob stopped working after exposure to water it may be possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or an electronic cleaner.

However, if the key fob still does not respond after cleaning it, then it is likely that the module is faulty and will need to be replaced. A malfunctioning receiver module could also cause the remote control key to not function. This is usually due to electromagnetic interference.

A defective electronic chip

The electronic chip that is in your key fob is a vital function in the anti-theft security system in your car. It sends out a signal the immobiliser unit of your vehicle to tell it whether the key is genuine. If the chip is damaged or damaged, your car will not start.

A damaged chip could be caused by interference signals from objects or weather conditions that are bad, or transmitters on the same frequency close to your vehicle. In this instance you'll need an entirely new key fob.

Contacts with the battery may be damaged.

The battery contacts on a key fob are very delicate and could be damaged when used for long periods of time. If they are bent, or damaged, the fob will not send any signals to the receiver modules in the vehicle.

Modern fobs are constructed with rubber seals in order to keep out water. Immersing them in water, even if just the slightest splash or drizzle, can damage the chip's electronic components.

The key fob houses the chip that connects to the vehicle's immobilizer system in order to start it. This system uses crypto coding systems in vehicles that are more modern or the red key system for older models. This chip will have to be replaced if defective.

Problematic 12 Volt Battery

A malfunctioning battery could cause the remote to cease to function. When this occurs, the car's computer system won't recognize that the remote is inside the vehicle.

Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops dramatically the time is now to replace it.

Set an electrical load for a short period of time on the battery to determine its capacity. This will eliminate 1% of the surface charges. After that, measure the voltage. The higher the capacity of the battery, the longer it can maintain its voltage. Ideal is to hold at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most common reason for a key fob to stop sending signals to vehicles. This problem can be solved by replacing the battery. However, it is important to purchase a battery that is the same voltage and size as the original.

Fobs aren't impervious to damage and can withstand a lot. The battery contacts and buttons could be damaged through rough handling.

A signal can also be impacted by other transmitters or objects which use the same frequency. A light control panel in your home, for instance, may interfere with key fobs that have the same bandwidth. This could affect the remote control of your car.

Afflicted OBDII scan tool

There are a variety of reasons why a scanner tool may not perform. Some are more complicated than others.

Professional scan tools permit mechanics to look over the car's networks and run a variety of self-tests. These tools can save you a lot of time, but are expensive and out of reach for most DIYers.

If your OBD2 scan tool won't power on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're all fine there is a chance that a fuse has blown. This is the most typical reason for failure of the scan tool. The most straightforward fix is to replace the fuse that is blowing up.
