Dead Coin Battery

A dead coin battery is the most common reason of a key fob not locking or unlocking your car. It usually displays signs before it dies such as a decreasing range or no power at all. It is simple to replace it with a new (CR2025) one from a local retailer. Be aware that using the wrong or unsuitable batteries could damage your key fob. Be sure that the replacement battery is the same size and voltage and also the same specification.

If your fob was exposed to clean water, such as rainwater or soapy water from the tap It is probable that corrosion has damaged the electronic chip. You could try cleaning the chip using isopropyl alcohol or an electronic cleaner to see if it helps but it is more likely that the chip has fried.

A new key fob is the simplest solution. They are readily available from major dealerships and can be installed by a qualified mechanic. They can also be bought on the internet through sites like ebay. The best method is to work on a flat, level surface with adequate lighting. It is easier to work with small parts.

Water Damage

If your key fob is wet from dropping it into the pool or throwing it in the wash you might think that it's gone but there's a chance. The problem begins when the circuit board inside the fob comes in contact with water. It is a great conductor and shorts components. It also accelerates the process of rust and corrosion.

Luckily, this is a simple issue to fix. Simply locate something absorbent and place it inside the fob - a paper towl or tissue work well. Then apply a cotton swab that has been soaked in isopropyl alcohol and wipe down the circuit board as well as other components to eliminate any residue of battery acid and contamination. Let the circuit board dry for some time in a dry and warm environment.

Replace the battery after the fob has dried by replacing it with a new one with the same dimensions and the same polarity ('+' (pointing upwards). The fob can be difficult opening to access the battery, however If you have a flat-head screwdriver, it should be easy to slide in. Once the fob is reassembled it should function as usual. If it does not work you may need to program it again or replace the module.

Radio Interference

If a keyfob functions properly, it transmits an audio frequency that is received by a module in your vehicle. However, if the signal is disrupted in any way, your key fob won't work properly. This may be due to things, weather conditions or other transmitters operating on the same frequency band near your car.

This could cause your key fob to not be able to activate the car's systems like the ignition switch, or the security system. In this instance it is recommended to replace the battery in your key fob.

A few LED lighting products that utilizes the same frequency as a remote control key fob may interfere with the signal, preventing it from reaching receiver modules. To avoid interference, the LED lights should be turned off or switched to a different frequency.

If the issue continues to persist after installing a new battery, the antenna on your key fob may be damaged or is malfunctioning. This is crucial because the antenna is responsible for transmitting a signal from the key fob to the receiver module. Using an OBDII scanner can assist in diagnosing the problem by revealing what's wrong with the system. The scanner will request details about your particular vehicle like the model and make along with the engine type and VIN number.

Faulty Receiver Module

The key fob is equipped with a receiver module which transmits signals for locking and unlocking. All on-board electronic components will cease to function if this module develops a problem. Reprogramming the key fob by an OBDII scan, or replacing it can help.

There are a few possibilities for the cause of this problem such as a dead coin battery water damage or signal interference. You can reset the on-board computer if you disconnect the 12 volt batteries for 15 minutes. This will draw out any remaining electrical energy that could cause issues. Remove the cable first from the negative terminal, then the positive terminal. After 15 minutes, reconnect the battery in reverse order beginning with positive first, and negative second.

The internal chip in the key fob can also be damaged by water or dirt. If your key fob stopped working after being soaked, clean it with isopropyl, or an electronics cleaner. After that, replace the battery. If it has stopped working after exposure to soapy or salty water, the chip is probably damaged and must be replaced.

Another possibility is a defective antenna module fuse that is sending the signal to lock or unlock to the vehicle. The fuse may be located in a variety of locations, based on the type of vehicle. For example, it could be under the rear Seat Car key chip, or in the trunk, or on the side of the dashboard.
