10 Things Your Competition Can Learn About Fiat 500 Keys

Fiat Panda Key Fob Replacement

fiat panda key fob replacement Panda key fobs contain an transponder chip that transmits signals to your car to open the doors and start the engine. However, the fob could stop working for several reasons.

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

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Choose a new button battery with the same size, voltage and specification as the original.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to being used again. The trick is to use the paper towel and soak it in isopropyl or an electronic cleaner.

If the key fob doesn't working despite not being exposed to water, it could be due to a problem in the receiver module or in the internal electronic chip. Reprogramming the keyfob using an OBDII scan can help in these instances.

Water Damage

If your key fob has gotten a bath in the puddle or pool or even a trip down the wash machine, you may have some water damage. It is usually possible to be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's a good idea to allow the fob to dry completely before putting in a new battery.

If your key fob isn't working even after replacing the battery and changing the program, you could have a problem with the receiver module. Reprogramming instructions are available for most vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset the computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the car's system. The chip will stop sending and receiving signals to the car when it is damaged. Dropping the key fob can result in this, as can water exposure. If your key fob stopped functioning due to water exposure, you may be able to fix it if you clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob still does not respond following cleaning, it is likely that the module is faulty and will require to be replaced. A defective receiver module could also cause the remote control key to cease functioning. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The chip inside your key fob plays a vital role in the anti-theft security system of your car. It transmits a message to the immobiliser inside your car to tell it whether the key is legitimate. Your car won't start when the chip is damaged.

A damaged chip could be caused by interference signals from other objects such as weather conditions, objects or transmitters on the same frequency close to your car. In this case the replacement fob will be required.

Contacts for the battery that are defective

The battery contacts in the key fob are fragile and are susceptible to damage by repeated use. If they're bent or broken the fob won't send any signals to the receiver modules inside the car.

Modern fobs have rubber seals that block out water. A splash of water or light rain is fine however, submerging them in saltwater may damage the chip's electronic components.

The key fob has an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. This system makes use of cryptocoding systems in modern vehicles, or the old red key for fiat 500 system in older ones. The chip must be changed if it is malfunctioning.

Problematic 12 Volt Battery

A faulty battery may cause the key fob to function. The car's system will not recognize the remote when this happens.

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

Place an electrical load for a short time on the battery to determine its capacity. This will take away approximately 1 percent of the charge on the surface. Then, you can measure the voltage. The better the battery's capacity is, the longer it will maintain its voltage. Ideal is that it stays close to 12 volts during several minutes.

Problems with Radio Signal

This is the most typical reason for the key fob to stop sending signals to cars. This issue can be resolved by replacing the battery. It is however important to purchase a battery that is the same size and voltage as the original one.

Fobs are subject to a lot of punishment, and aren't indestructible. Contacts on batteries and buttons can be damaged through rough handling.

Other objects or transmitters using the same frequency could also interfere with the signal. A light-control system in your home, for instance could interfere with key fobs using the same frequency. This could cause interference with your car's remote control.

The tool is not working properly. OBDII scan tool

There are many reasons why scanner tools may not perform. Certain are more complicated than others.

Professional scan tools let mechanics to look over the car's network, and run various self-tests. These tools can save a lot of time, but they're expensive and out of reach for most DIYers.

If your OBD2 scanner isn't turning on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape, it's likely that a fuse has blown. This is among the most common causes of a scan tool failing. The easiest fix is to replace the fuse that has been blown.
