If the new battery fails to solve the issue it could be because there is a problem with the fob that requires professional assistance. Key fobs can be affected by many issues, including signal interference, worn out buttons or buttons, water damage, receiver modules and dead batteries. To determine whether any of these could be the reason behind your issue, it's helpful to have an extra key fob that is working to identify any possible causes of the problem.
The 12 volt battery inside the key fob is crucial to power the on-board electronics, which includes the central locking and remote keyless systems. The remote keyless system won't work when the battery is damaged, or if it has lost its charge. To test the battery's 12 volts remove it for a few minutes by taking off the negative cable first and then the positive cable. This will drain all of the residual electricity in the circuit and then reset it, allowing the remote keyless system to work in a way it was before.
If you have an additional key fob, consider reprogramming the original one to see if this solves the issue. The process for reprogramming the key fob is easy and involves turning on the ignition and leaving it in, pressing the unlock button five times, with a one second interval between each press, and then waiting 6 seconds until the horn sounds to start the coding process.
Worn Buttons

Signal interference is another potential problem. This can be caused by radio transmitters in close proximity, objects, or even the weather. This could cause your key fob to only work when it is located close to your vehicle. The solution to this is to move away from the source of interference.
Water Damage

This kind of issue can be difficult to determine in certain situations because it is not always evident. If you notice that your key fob is only working when it's in close proximity to the vehicle, that's an indication of a signal interference issue.
Receiver Module Issues
If your key fob isn't working it could be because the receiver module has developed an issue. It is the chip that communicates with the other modules in your vehicle to lock and unlock the doors. If the chip fails and fails to function, you'll need to replace it.
It could also be caused by signal interference. If your key fob is too close to other transmitters, their signals will be in conflict and cause it to cease functioning. This can include neighboring radio towers, TV or mobile phone antennas and even appliances in the home. If you suspect this is the problem Try shifting your keyfob away from any sources and test if it works again.
Make sure that the clips made of metal that hold the key fob in place aren't damaged or loose. They keep the battery in place and complete the circuit. If they're not tight or damaged the battery won't receive any power and the remote won't function. To prevent damaging the keyfob, you must also replace the battery that was damaged with a brand new one that has the same voltage and same size.
Another reason that your key fob isn't working is because the key fob was exposed to water or salt.
