10 Things Competitors Learn About Fiat 500 Keys

Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain an transponder chip that transmits signals to your car to open the doors or start the engine. The fob could stop working for a variety.

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

Dead Coin Battery

If your key fob battery is dead, the first step is to replace it. Use a brand new button battery that has identical in size, voltage and specifications like the previous one.

If the key fob was exposed to water (such as rain or saltwater at the beach) it must be cleaned before being used again. A paper towel soaked in alcohol or electronic cleaner will do the trick.

If the key fob is not working even though it is not exposed to water, it could be due to a malfunction in the receiver module or internal electronic chip. Reprogramming the keyfob with an OBDII scan could aid in these situations.

Water Damage

If your key fob's battery has taken an immersion in the pool or puddle, or taken a trip down the washing machine, you may have some water damage. It's usually possible to be able to get it back up and running by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is best to let the board completely dry prior to installing a battery.

If your key fob stopped working, even after replacing the battery and changing the program, you could have a malfunctioning receiver module. You can find instructions for changing the programming of most remote keys on YouTube or consult the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip which communicates with the vehicle's system. If this chip becomes damaged, it will no longer transmit and receive signals to the vehicle. This can be caused by dropping the key fob or by water exposure. If fiat punto key replacement have purchased has stopped working due to water exposure it is possible to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob is still unable to not respond even after cleaning it it is likely that the module is defective and must be replaced. A damaged receiver module may also cause the remote control key to not 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 car. It transmits a message to the immobiliser in your car to tell it if the key is valid. Your car won't start in the event that the chip is damaged.

A faulty chip can also be caused by interference signals from other objects such as weather conditions, objects or transmitters operating on the same frequency as your vehicle. In this scenario the replacement fob will be needed.


Contacts to the battery are not working properly.

The battery contacts in a key fob are very delicate and may be damaged 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 made with rubber seals to keep out water. A splash of water or a light rain is fine but submerging them into saltwater may cause damage to the chip's electronic components.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to begin it. This system makes use of cryptocoding systems in vehicles that are more modern, or the old red key system used in older ones. If the chip is not working properly it will have to be replaced.

Problems with 12 Volt Batteries

A damaged battery could cause the key fob to work. The car's computer may not recognize the remote if this occurs.

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly, it is time to replace the battery.

Put an electrical load for a short period of time on the battery to determine its capacity. This will take away about 1% of the charge on the surface. Then, you can measure the voltage once more. The longer the battery can hold its voltage more effectively, the greater its capacity. Ideal is to hold close to 12 volts for several minutes.

Problems with Radio Signal

This is the most typical reason for keys not sending signals to the car. The issue can be fixed by replacing the battery. It is important to buy batteries that have the same voltage and dimensions as the original.

Fobs take a lot of punishment, and aren't indestructible. The battery buttons and the contacts are fragile and are susceptible to being bent or broken with rough usage.

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

Afflicted OBDII scan tool

There are many reasons why a scan tool may not work. Some are more complicated than others.

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

If your OBD2 scanner isn't turning on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK there is a chance that a fuse has been blown. This is the most common reason for failure of the scan tool. It is usually easy to fix the problem by replacing the fuse blowing up.
