Infra Red Remote
If your remote is older then it may need cleaning.
Step No1 Get a video camera, look through the camera and put the remote infront of it and press the button. If its working you will see the infra red light through the camera.
Step 2 Of its not working take the remote apart and clean the contacts & batteries. If you have a volt meter measure the voltage across the batteries sould be more than 1.2 volts. If they are at all suspect byuy some new ones, then test again with the camera.
Step 3 A new remote in the UK is £55.00 but you need to produce passport, car registration and licence to order one.
Im affraid I dont have any ideas to check the car sensor side.
Good Luck
