fiat 500 spare Key cost Panda Key Fob Replacement

fiat doblo key programming Panda keyfobs are equipped with a transponder which transmits an electronic signal from the fob to the car in order to unlock doors or turn on the motor. However, the fob could not function due to a variety of reasons.

A dead battery for the coin is the most frequent cause of key fob malfunctions. Other causes are water damage, a faulty receiver module, and signal interference.

Dead Coin Battery

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

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it needs to be cleaned before it is able to be used again. A paper towel soaked in alcohol or electronic cleaner can work wonders.

If the key fob hasn't been exposed to water but still does not work it could be due to an issue with the receiver module or an internal electronic chip. In these situations it is possible that reprogramming the key fob using an OBDII scanner can aid.

Water Damage

If your key fob's battery has taken a bath in the puddle or pool, or taken a trip to the washing machine, you may have some water damage. It is usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely before putting in a new battery.

If your key fob has stopped working even after replacing the battery and changing the program, you could have a malfunctioning receiver module. You can find information on reprogramming most vehicles' remote keys on YouTube, or consult your owner's manual. You can also reset the car's computer using 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 damaged. A key fob falling off can cause this, as can exposure to water. If your key fob stopped functioning due to water exposure, you may be able to fix it if clean the chip with electronic cleaner or isopropylethanol.

If the key fob continues to not respond following cleaning, there is a good chance that the receiver module is not functioning properly and needs to be replaced. A malfunctioning receiver could cause the key to stop working. This is typically caused by electromagnetic interference.

A defective electronic chip

The electronic chip in your key fob plays a vital function in the anti-theft security system of your car. It transmits a message the immobiliser in your car to tell it whether the key is genuine. If the chip is damaged or broken, the car won't start.

A malfunctioning chip can be caused by interference caused by objects, bad weather or transmitters in the vicinity of your vehicle. In this case, a new fob will be required.

Contacts to the battery are not working properly.

The battery contacts in a key fob are very fragile and are susceptible to damage with hard usage. If they're bent or broken, the fob won't send any signals to the receiver modules inside the vehicle.

Modern fobs are equipped with rubber seals to keep out water. Submerging them in water, even if just small splash or drizzle could damage the electronic chip.

The key fob has the chip that connects to the vehicle's immobilizer in order to allow it to start. This system uses crypto coding systems in modern vehicles or the red key system used in older ones. If the chip is damaged it will have to be replaced.

Poor 12 Volt Battery

A malfunctioning battery could cause the key fob to function. When this occurs the car's computer cannot recognize that the remote is inside the vehicle.

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly it is time to replace the battery.

To test the battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will remove about 1% of the surface charge. After that, measure the voltage. The longer a battery is able to keep its voltage steady greater is its capacity. Ideal is that it stays close to 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most typical reason for the key fob not sending signals to vehicles. The battery can be replaced to solve this issue. But, it is essential to select a replacement battery that is the same size and voltage as the original one.

Fobs aren't indestructible and can be damaged by a lot. The battery contacts and buttons are delicate and can be bent or broken by rough use.

Other transmitters or objects operating on the same frequency may also interfere with the signal. A light control panel in your home, for instance can interfere with key fobs which use the same frequency. This can interfere with the remote control of your car.

Faulty OBDII scan tool

There are many reasons why a scanner could not function. Some are more complicated than others.

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

If your OBD2 scan tool won't power on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they are all OK, a fuse may have been blown. This is one of the most frequent causes of failures in the scan tool. The simple fix is usually to replace the fuse that is blowing up.
