Dead Coin Battery


A dead coin battery is the most typical cause of a key fob not locking or unlocking your car. It will usually show indications before it dies, such as a decreased range or no power at all. It is simple to replace with a brand new one (CR2025) from an area supermarket. Be aware that using the wrong or incompatible batteries can damage your key fob. Make sure that the battery you replace is the same size and voltage, as well as the same specifications.

If your fob has been exposed to clean water, such as rainwater or soapy tap water it is possible that corrosion has caused damage to the electronic chip. You may try cleaning the chip with isopropyl alcohol or an electronic cleaner to see if it helps but it is likely the chip is damaged.

The simplest option is to buy an entirely new key fob. Major car dealers sell them and they can be installed by a seasoned mechanic. They can also be purchased on the internet from sites like ebay. It is best to work on a surface with adequate lighting. It is much easier to work on small parts. This will also help you to avoid putting things back in the wrong place.

If your fob's key gets damaged by dropping it in the pool or by slipping it in the washing machine, you may think that it's lost but there's a chance. The issue begins when the circuit board within the fob is in contact with water - it makes an excellent conductor and cuts off components. It also speeds up the process of rust and corrosion.

Fortunately, this is not difficult to fix. Find something absorbent to put inside the fob. A paper towel or tissue will be ideal. Then, use a cotton swab dipped in isopropyl ethanol to wipe down the circuit board and other components to get rid of any residue of battery acid and contamination. Let the fob air dry in a dry, warm environment for several weeks.

When the fob has been drained, replace the battery with a new one of the same size and the same polarity ('+' pointing upwards). It isn't easy to open the fob to get access to the battery, but if you have a small flat-head screwdriver available, it should be able to slide into easily. Once the fob is assembled and working, it should operate as normal. If it doesn't work you may need to program it again or replace the module.

Radio Interference

When a keyfob is working correctly, it emits an audio frequency that is received by a module in your vehicle. If the signal is interrupted the key fob will not function. This could be due factors like weather conditions, objects, or other transmitters operating in the same frequency range near your car.

In this scenario it is recommended to replace the battery on your key fob. It is best to replace the battery on your key fob.

A few LED lighting products that uses the same frequencies as a key fob for remote control could interfere with the signal, stopping it from reaching receiver modules. The LED's lighting needs to be turned off or switched to a different frequency to be able to avoid interference.

If the issue continues to persist after installing a new battery, the antenna of the key fob might be damaged or not functioning properly. The antenna is responsible for transmitting a signal between the key fob and the receiver module. The OBDII scanner is able to aid in identifying the issue by revealing what's wrong with the system. The scanner will ask for details about your particular vehicle including the model and make as well as the engine type and VIN number.

Faulty Receiver Module

The key fob is equipped with a receiver module that transmits the signals for lock and unlock. If the receiver module is damaged then all the on-board electronics will cease to function. Reprogramming the key fob with an OBDII scan or replacing it can help.

This issue could be caused by a dead coin cell battery, water damage or signal interference. You can reset the onboard computer if you disconnect the 12 volt batteries for about 15 minutes. This will draw out any remaining electrical energy that could be causing issues. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, connect the battery in reverse order beginning with positive first, and negative second.

The internal chip inside the key fob could be damaged by dirt or water. If the key fob you purchased stopped working after being wet, wash it with isopropyl, or an electronics cleaner. Then reinstall the battery. If it stops working after exposure to salty or soapy water the chip is likely damaged and must be replaced.

Another possibility is an inoperable antenna module fuse that transmits the lock / unlock signal to the vehicle. Depending on your model the fuse could be located in one of the many locations including the engine bay, to the left of the dashboard, under the rear seat, or in the trunk.
