The vehicle transmits radio waves to locate the keyless remote when locking/  
unlocking the doors, opening the boot, or to start the engine.  
Communication between the keyless remote and the  
vehicle consumes the keyless remote's battery.  
The keyless remote battery lasts about two years. This  
changes by how often you use the remote.  
The battery is consumed whenever the keyless  
remote is receiving strong radio waves. Avoid placing  
it near electrical appliances such as televisions and  
personal computers.  
In the following cases, locking/unlocking the doors or opening the boot or starting  
the engine may be inhibited or operation may be unstable:  
Strong radio waves are being transmitted by nearby equipment.  
You are carrying the keyless remote together with telecommunications  
equipment, laptop computers, mobile phones, or wireless devices.  
A metallic object is touching or covering the keyless remote.
