A dead coin battery is the most frequent reason for malfunctioning locked keys in car boot fiat punto. Other causes include water damage a faulty receiver module, and signal interference.

Dead Coin Battery

If the battery in your key fob is dead, the first thing to do is replace it. Use a brand new button battery that has exactly the same size, voltage and specifications as the previous one.

If the key fob was exposed to water, like a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner can be the solution.

If the key fob isn't working despite being not exposed to water it could be due a malfunction in the receiver module or in the internal electronic chip. In these situations you can reprogramme the key fob with an OBDII scanner could help.

Water Damage

It is possible to get water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually be able to get it back up and running by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the fob completely dry before putting in the battery.

You may have a faulty module in the event that your key fob stops working after replacing the battery or replacing it with. There are reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in the owner's guide. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the car's system. This chip will stop sending and receiving signals to the car when it is damaged. A key fob falling off can cause this, as can water exposure. If the key fob you have purchased has stopped working due to exposure to water or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob still does not respond after cleaning it, there is a good chance that the component is damaged and will need to be replaced. A malfunctioning receiver module could also cause the remote control key to stop working. This is often 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 sends a signal to the immobiliser unit in your car to determine whether or not the key is in fact valid. Your car will not start when the chip is damaged.

A damaged chip could be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this scenario, you will need an entirely new key fob.

Contacts to the battery are not working properly.

The battery contacts in the key fob are delicate and can get damaged when used for long periods of time. If they are damaged or bent, the key 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. Submerging them in water even if it's only a light drizzle or splash could damage the chip's electronic circuit.

The key fob has chips that communicate with the vehicle's immobilizer system to begin it. The system relies on cryptocoding systems in vehicles that are more modern, or the old red key system in older models. This chip will need to be replaced if faulty.

A faulty 12 Volt battery

A damaged battery can cause the remote to cease working. When this happens the car's computer cannot recognize that the remote is in the vehicle.

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

To test a battery's capacity put an electrical load on it for a couple of minutes. This will eliminate approximately 1% of the charge on the surface. Then take another measurement of the voltage. The better the battery's capacity is, the longer it will maintain its voltage. Ideal is to hold at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most common reason for a keyfob that ceases how to unlock fiat 500 boot without key send signals to the fiat car key. The battery is able to be replaced to resolve this issue. But, it is essential to purchase a battery that is the same voltage and size as the original one.

Fobs endure a lot of abuse, but they're not indestructible. Contacts and buttons on batteries can be damaged through rough handling.

Other transmitters or objects that use the same frequency can interfere with a signal. A light control panel in your home, for example, may interfere with key fobs using the same bandwidth. This can interfere with the remote control in your car.

Afflicted OBDII scan tool

There are a number of reasons why a scanner may not work. Some are more complex than others.

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

If your OBD2 scan tool won't power on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're all fine it could be that a fuse has failed. This is one of the most frequent causes of scan tool failure. The most straightforward fix is to replace the fuse which has blown.(Image: https://www.thekeylab.co.uk/wp-content/uploads/sb-instagram-feed-images/311170119_2306394586188303_2849487588620745484_nlow.jpg)
