Why is my vw Tiguan keyless Entry not working?

The most common problem with these car key fobs is that the batteries just go dead over time, in which case replacing the battery should fix the problem. Other key fob remote problems are more complicated, but it's still possible to fix them. Take the key fob apart and check for broken contacts or misaligned buttons.Having a key fob can allow You to lock Your car when You forgot it from a long distance to prevent any near-future theft. It also allows for the driver to signal the car's alarm in the event of an emergency. They are more secure than the conventional lock and key and much more reliable than having to use a digital keypad to type in a code.
