Hello one, hello all.
My remote central locking doesn't work - never did since I got the car (1999 D8)

though the physical central locking system works well. It's a 2-button fob. The bigger button is gone, but the smaller button is still there. When pressed the red LED lights up but nothing happens in the locking system, and I can't get the remnants of the big button pressed. The guy at Peugeot was going to run me £250 for a whole new key etc. Seeing as I only paid £375 for the car - no thanks! Not for a luxury. How hard would it be to do this myself if I get a new fob?
Second, I'd like to make the passenger electric window 1-touch, just like the driver's side. Possible?
And last but not least, a maybe more ambitious project - I'd like to install a turbo boost dial somehow. It's a 2.0L HDi, if that helps.
