Fiat Punto Car Key Replacement Panda key fobs contain an transponder chip that transmits the signal to your vehicle to open the doors and start the engine. However, the key fob may be inoperable due to various reasons.

The most common cause of key fob failure is the battery of the coin is dead. Other causes include water damage a faulty receiver module, and signal interference.

Dead Coin Battery

Replace the battery if the key fob is dead. Use a brand new button battery that is identical in size, voltage, and specification as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to using it again. The trick is to use a paper towel that has been soaked in isopropyl, or electronic cleaner.

If the key fob isn't working despite being 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 with an OBDII scan could help in these instances.

Water Damage

If your key fob took a bath in the puddle or pool or even a trip to the washing machine, you may have some water damage. It's generally possible to repair it by getting rid of the batteries and cleaning the circuit board using rubbing alcohol. It is a good idea to allow the fob to dry completely before putting in a brand new battery.

You may have a faulty module if your key fob stops working after replacing the battery or reprogramming. You can find reprogramming instructions for most remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with a chip that connects to the car's system. This chip will stop sending and receiving signals to the car if it becomes damaged. This could be due to dropping the key fob, or due to exposure to water. If your key fob isn't functioning due to water exposure it is possible fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob still does not respond following cleaning, it is likely that the component is damaged and will require to be replaced. A damaged receiver can cause the key to not work. This is usually due to electromagnetic interference.

A defective electronic chip

The electronic chip inside the key fob is a vital part of the anti-theft system in your car. It sends a signal to the immobiliser inside your car to inform it whether the key is genuine. If the chip is damaged or broken, your vehicle won't start.

A defective chip could be caused by interference caused by objects, bad weather or transmitters in the vicinity of your vehicle. In this scenario you'll require a new key fob.

Faulty Battery Contacts

The battery contacts on the fob's key can be damaged through heavy use. If they're bent or broken, the fob won't send any signals to receiver modules in the vehicle.

Modern fobs feature rubber seals to keep out water. Immersing them in water, even if just a light drizzle or splash can harm the chip's electronic circuit.

The key fob has the chip that connects to the vehicle's immobilizer in order to allow it to start. The system is based on the old red keys for Fiat Punto Car Key Replacement older vehicles, or the cryptocoding system that is used in modern vehicles. This chip will have to be replaced if damaged.

Problematic 12 Volt Battery

A damaged battery could cause the key fob to function. If this happens the car's computer won't recognize that the remote is within the vehicle.

Before replacing the battery, you should test it with a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly the time is now to replace it.

Install an electrical charge for a short time on the battery to gauge its capacity. This will take off about 1% of the charge on the surface. Then, you can measure the voltage once more. The longer a battery is able to hold its voltage greater is its capacity. Ideal is that it stays close to 12 volts during several minutes.

Problems with Radio Signal

This is the most common reason for a key fob that ceases to send signals to the car. This problem can be solved by replacing the battery. However, it is crucial to buy a new battery that has the same size and voltage as the original.

Fobs can take a lot abuse, but they're not impervious to destruction. The battery contacts and buttons are delicate which means they could be bent or broken with the force of.

Other transmitters or objects that use the same frequency can disrupt 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 in your car.

Afflicted OBDII Scan Tool

There are many reasons why scanners may not function. Some are more complicated than others.

Professional scan tools let a mechanic observe the car's network, and fiat punto car key Replacement run various self-tests. These tools can save a lot of time, but are expensive and out of reach for most DIYers.

imageIf your OBD2 scan tool won't power on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape the chances are that a fuse is blowing. This is the most common reason for a scan tool to fail. It is typically simple to fix the issue by replacing the blown fuse.
