With a thumb nail or small screwdriver with a flat-headed head (A) lift upwards the key fob battery compartment cover (B). Replace the coin battery CR2025 and ensure it is placed in the correct direction and polarity.
Dead Coin Battery
A dead coin battery is the most common reason of a key fob not locking or unlocking your car. It will usually show indications before it dies, like a decrease in range or no power at any time. It is easy to replace it with a brand new (CR2025) one from a local retailer. It is important to be aware that using the wrong or non-compatible batteries can damage your key fob. Make sure that the battery you purchase is the same size, specification and voltage as the previous one.
If your fob has been exposed to clean water, for example rainwater or soapy water from the tap It is likely that corrosion has damaged the chip's electronic circuit. You might try cleaning your chip with alcohol or an electronic cleaner to see if it helps but it is most likely that the chip is damaged.
A new key fob is the most straightforward solution. The majority of major car dealers sell key fobs and they can be installed by a seasoned mechanic. You can also purchase them online, like on eBay. It is best to work on a surface with adequate lighting. This makes it easier to work on small parts inside. This will also allow you to avoid putting things back into the wrong place. Always work on your key fob in a place that is secure and safe.
Water Damage
If your key fob gets wet from dropping it into the pool or fumbling it in the washing machine, you may think that it's gone but there's still hope. When the circuit board in the fob is exposed to water, it develops an electrical conductor, which shorts the components. It also accelerates the process of rust and corrosion.
This is an easy solution. Find something absorbent to put inside the fob. A tissue or paper towel will be a good choice. Make use of a cotton swab and isopropyl to wash the circuit board and any other components. Allow the board to dry for a few days in a dry and warm environment.
Once the fob is dried out and the battery is replaced with a new one (of the same size and the same polarity ('+' pointing upwards). It is a challenge to open the fob to reach the battery, however if you have a small flat-head screwdriver handy it should slide in easily. After the fob has been reassembled, it should work as normal. If it doesn't, then you'll need to reprogram it or replace the receiver module.
Radio Interference
When a key fob working correctly, it sends an audio frequency signal that is picked up by the receiver module in your car. If the signal is distorted in any way the key fob will not function as expected. seat leon key programming could be caused by objects, weather conditions or other transmitters operating within the same frequency band close to your vehicle.
In this situation, it is best to replace the battery in your key fob. In this scenario it is recommended to replace the battery inside your key fob.
Some LED lighting from the aftermarket that uses the same frequency as a remote key fob might interfere with the signal and prevent it from reaching the receiver modules. The LED's lighting needs to be switched off or changed to a different frequency in order to be able to avoid interference.
If the issue is still present after replacing the battery, the antenna of your key fob may be damaged or not functioning properly. This is because the antenna is responsible for transmitting an indication from the key fob to the receiver module. A scan of the OBDII can assist in diagnosing the issue by revealing what's wrong with the system. The scanner will ask you for details about your vehicle, such as the make and model as well as the engine type and VIN number.
Faulty Receiver Module
The key fob features a receiver module which transmits signals for locking and unlocking. If this module develops a fault and the on-board electronic components will stop functioning. If this is the case then reprogramming the module using an OBDII scanner or replacing the key fob may assist.
This problem can be caused by a dead battery in the coin-cell either from water damage or signal interference. You can reset the onboard computer if you disconnect the 12 Volt batteries for 15 minutes. This will drain any remaining power that could be causing problems. Start by removing the cable from the negative terminal first, then the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive, then negative second.
Water or dirt can also cause damage to the internal chip of the key fob. If your key fob stops working after being soaked, clean it with isopropyl or electronics cleaner. Then reinstall the battery. If it has stopped working after exposure to soapy or salty water, the chip is probably fried and will need to be replaced.
A defective antenna module fuse could also be the reason. It is the fuse that sends an electronic signal to the vehicle to lock or unlock. The fuse can be found in a variety of locations, based on the type of vehicle. For instance, it could be under the rear seat or trunk, or on the side of the dashboard.
