fiat 124 spider key fob not working Panda Key Fob Replacement

fiat punto key stilo key; web link, Panda key fobs contain an transponder chip that transmits an alert to your car to unlock the doors or start the engine. The fob can stop functioning due to a variety reasons.

The most common cause of key fob failure is the battery of the coin is dead. Other causes include water damage or a malfunctioning module and interference signals.

Dead Coin Battery

Replace the battery if your key fob is dead. Make use of a button cell battery with the same voltage, size, and specification as your old one.

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

If the key fob isn't working even though it is not exposed to water, it could be due to a malfunction in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob using an OBDII scan may help in these cases.

Water Damage

If your key fob has taken an immersion in the pool or puddle, or taken a trip down the washing machine, you could be suffering some water damage. It's generally possible to repair it by taking out the batteries and cleaning the circuit board using ruby alcohol. It is recommended to let the fob completely dry prior to installing a battery.

If your key fob has stopped working, even after replacing the battery and reprogramming it, you may have a malfunctioning receiver module. There are instructions for reprograming the majority of remote keys on YouTube, or consult the owner's manual. 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 connects to the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. This could be due to dropping the key fob or through exposure to water. If your key fob stopped functioning due to exposure to water, you may be able to fix it if clean the chip with electronic cleaner or isopropylethanol.

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

Electronic chip that is malfunctioning

The chip that is embedded in your key fob is an essential element of the anti-theft device in your car. It transmits a signal to the immobiliser unit inside your car to determine whether or not the key is in fact valid. Your car won't start in the event that the chip has been damaged.

A faulty chip may also be caused by interference from objects, bad weather or transmitters close to your vehicle. In this case you'll need an entirely new key fob.

Contacts with the battery may be damaged.

The battery contacts of the key fob could be damaged by heavy usage. If they're bent, or damaged, the fob will not transmit any signals to receiver modules in the vehicle.

Modern fobs feature rubber seals that block out water. Immersing them in water, even if just the slightest splash or drizzle could harm the electronic chip.

The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle to start it. The system uses the old red fiat punto keys that were used in older vehicles or the cryptocoding system that is used in newer vehicles. If the chip is damaged it must be replaced.

Problematic 12 Volt Battery

A faulty battery may cause the key fob to function. When this occurs the car's computer won't recognize that the remote is inside the vehicle.

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

Install an electrical charge for a few seconds on the battery to test its capacity. This will take off about 1% of the charge on the surface. Then, measure the voltage once more. The better the battery's capacity and the longer it can maintain its voltage. The ideal scenario is to keep it close to 12 volts several minutes.

Radio Signal Faulty Radio Signal

This is the main reason behind a key fob that stops sending signals to the car. This problem can be solved by replacing the battery. It is essential to purchase an identical battery voltage and dimensions as the original.

Fobs endure a lot of abuse, and they aren't indestructible. The battery buttons and contacts are brittle and are susceptible to being bent or damaged by rough use.

Other transmitters or objects operating on the same frequency may also interfere with the signal. A light-control system in your home, for instance could interfere with key fobs that have the same bandwidth. This could affect the remote control of your car.

Faulty OBDII Scan Tool

There are a number of reasons why a scanner could not function. Some are more complex than others.

Professional scan tools allow a mechanic to look over the car's networks and run a range of self-tests. These tools can save time, but are expensive and out of reach for the majority of DIYers.

If your OBD2 scanner doesn't work Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition the fuse could have been blown. This is the most frequent reason for a scan tool to fail. The easiest fix is to replace the fuse which has blown.
