not sure if in the right place, but i have a vtr mk1, it has remote central locking but doesn't not work all the time. when i am sat in the car and point the remote to the sensor it works fine, when i get out the light on the remote flashes when i press the button, but nothing happens , the car doesnt lock. occasionally the car does lock when im outside but that's about it. can any one help me please (o and i have put new batteries in the remote)
