Pay Attention: Watch Out For How Fiat 500 Keys Is Taking Over And What…

Fiat Panda Key Fob Replacement

fiat 500 spare key Panda key fobs contain a transponder chip which sends signals to your car to open the doors and start the engine. However, the key fob may not function due to a variety of reasons.

A dead coin battery is the most frequent reason for malfunctioning keys. Other causes are water damage as well as a defective module and interference signals.

Dead Coin Battery

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

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned prior to using it again. A paper towel soaked with isopropyl alcohol or electronic cleaner will work wonders.

If the key fob has not been exposed to water, but still does not work it could be due to a problem with the receiver module or an internal electronic chip. In these instances it is possible to re-programme the key fob using an OBDII scanner may assist.

Water Damage

There could be water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to get it back in working order by removing the batteries and cleaning the circuit board with ruby alcohol. It is recommended to let the board completely dry before installing batteries.

You could have a damaged module if your key fob stops working after replacing the battery or updating. You can find reprogramming procedures for most vehicles' remote key fobs on YouTube or in the owner's manual. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip which communicates with the vehicle's system. If the chip is damaged, it will no longer transmit and receive signals to the vehicle. A key fob falling off can cause this, as could water exposure. If your key fob has stopped working due to water exposure and you are unable fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob won't respond to cleaning, it is likely that the module is in a fault and needs to be replaced. A defective receiver module could also cause the remote control key to stop working. This is typically caused by electromagnetic interference.

A defective electronic chip

The chip that is embedded in your key fob is a vital component of the anti-theft systems in your car. It transmits a message the immobiliser in your car to determine whether the key for fiat 500 is legitimate. The car will not start in the event that the chip is damaged.

A malfunctioning chip could be caused by interference signals from objects or weather conditions that are bad, or transmitters on the same frequency near your car. In this case it is likely that a new fob would be needed.

Contacts to the battery are not working properly.

The battery contacts of the key fob are delicate and could be damaged through repeated use. If they are damaged or bent, the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs are constructed with rubber seals that keep out water. Immersing them in water, even if it's only small splash or drizzle, can damage the chip's electronic components.

The key fob contains chips that communicate with the vehicle's immobilizer in order to start it. The system relies on cryptocoding systems in vehicles that are more modern as well as the traditional red key system for older models. This chip will have to be changed if it is faulty.

Faulty 12 Volt Battery

A defective battery can cause the key fob not to function. The car's computer won't recognize the remote when this happens.

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

To test a battery's capacity, place an electrical load on it for a couple of minutes. This will take away 1% of the surface charges. Then, test the voltage again. The longer a battery can keep its voltage steady greater is its capacity. Ideally, it should remain close to 12 volts several minutes.

Faulty Radio Signal

This is the most common reason for the key fob not sending signals to cars. The battery is able to be replaced to resolve this problem. However, it is important to purchase a battery with the same size and voltage as the original.

Fobs can take a lot punishment, and aren't indestructible. The battery buttons and contacts are delicate and are susceptible to being bent or damaged by rough usage.

Other transmitters or objects that use the same frequency can also interfere with a signal. A light-control panel at your home, for instance, may interfere with key fobs that have the same bandwidth. This could interfere with the remote control in your car.

Faulty OBDII Scan Tool

There are a number of reasons why a scan tool might not work. Some are more complex than others.

Professional scan tools let a mechanic observe the car's network and run various self-tests. These are great time savers, however they are also extremely expensive, out of the range of most DIYers.

If your OBD2 scan tool isn't turning on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition the chances are that a fuse has been blown. This is among the most frequent causes of failures in the scan tool. It is usually easy to fix the problem by replacing the fuse that has blown.
