Dead Coin Battery

The most common reason for a key fob to not lock or unlock your seat car key is a dead coin battery. It is likely to show indications before it dies, such as a decreased range or no power at all. It is easy to replace it with a brand new (CR2025) one at your local grocery store. Be aware that faulty or unsuitable batteries can damage the key fob. Make sure that the battery you replace has the same size and voltage and also the same specification.

If your fob has been exposed to pure water, such as rainwater or soapy water from the tap, it is likely that corrosion has damaged the chip's electronic circuit. You could clean the chip with isopropyl or electronic cleaners to see if it can help, but that the chip has been damaged.

The simplest solution is to get a new key fob. The majority of major car dealers sell them and they can be installed by an experienced mechanic. You can also buy them online, like on eBay. The best method is to work on a flat surface that has good lighting. This will make it easier to work on the smaller parts inside. You'll also be able to avoid putting something in the wrong location. Always work on the key fob in a secure and safe area.

Water Damage

You may think that your key fob is lost if you drop it in an unintentional pool or accidentally wash it. But there's a way to salvage it. When the circuit board on the fob is exposed to water, it transforms into a conductor that shorts out the components. It also speeds up corrosion and rust.

Fortunately, this is easy to fix. Find something absorbent to put inside the fob. A tissue or paper towel would be a good choice. Make use of a cotton swab and isopropyl to clean the circuit board, as well as any other components. Let the fob air dry in a warm, dry environment for several weeks.

Once the fob is been drained and the battery is replaced with a new one (of the same size and the same polarity ('+' directed upwards). The fob can be difficult to open to access the battery, but if you keep a flat-head screwdriver in your toolbox it will be a breeze to slide in. Once the fob has been put back together, it should work as normal. If it does not work you may need to program it again or replace the module.

Radio Interference

If a keyfob functions properly, it sends out a radio signal that is received by a receiver module in your vehicle. If the signal is disrupted the key fob will not function. This could be due to objects, weather conditions, or other transmitters that operate at the same frequency close to your car.

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

Some aftermarket LED lighting that utilizes the same frequency as a remote key fob might interfere with the signal and prevent it from reaching the receiver modules. To avoid interference, the LED light must be switched off or to an alternative frequency.

If you have a brand new battery in your key fob and the problem persists, it is possible that the antenna of your key fob is damaged or inoperable. This is important because the antenna is responsible for sending signals from the key fob to the receiver module. An OBDII scanner can aid in diagnosing the issue by telling you what is wrong with the system. The scanner will ask you for details about your car including the model, make, engine type and VIN number.

Faulty Receiver Module

The key fob contains the receiver module which transmits the signals for lock and unlock. If the receiver module is damaged and the on-board electronics will cease to function. Reprogramming the key fob by an OBDII scan, or replacing it may help.

This problem could be caused by a dead coin-cell battery or a water damage or signal interference. Try resetting the on-board computer by disconnecting the battery 12 volts for 15 minutes. This will drain any residual power that may be causing issues. Begin by removing your cable from the negative terminal first, followed by the positive terminal. After 15 minutes, connect your battery in reverse order. First positive, then negative next.

The internal chip inside the key fob may be damaged by water or dirt. If your key stopped working after getting wet, wash the electronic component with isopropyl alcohol or an electronics cleaner before installing the battery. If it stopped working after exposure to soapy or salty water the chip could be damaged and should be replaced.

A faulty antenna module fuse may also be the cause. It's the fuse that sends an alert to the vehicle to lock or unlock. The fuse could be found in various places, based on the type of vehicle. For instance it could be beneath the rear seat car key replacement or trunk, or on the side of the dashboard.
