Right then it's about time I sorted the lock on my car door so i need to know how to get the old lock out and put a new one in, I've heard you have to remove the whole window frame, is this correct?

If somebody could give me a step-by-step guide I would be extremely grateful!

Thanks

2 or 4 door

Oops sorry it's a 2-door, early type with a lock only on the driver's side

I am just about to undertake this very same operation. I'll let you know how I go. If you've already done yours, any useful tips?

Alrighty, first of all allow about 3 hours.
Wind the window down.
Remove the window regulator and door handle.
Remove the door card.
There are 4 bolts to and 2 nuts remove to release the window frame.
3 bolts on the door edge (the bit closest to the door pillar when it's shut), the bolts are accessed through some circular cut outs.
1 bolt below where the window regulator would be, it has a nut behind it so make sure you don't drop it into the door.
2 nuts and spacers underneath the quarter light (in the most inaccessible place you could imagine).
Once you have all of those nuts, bolts and spacers removed, with quite a bit of jiggling, swearing and persuasive thumps the window frame should lift out. You could also dismantle the window frame by undoing all the screws in the top corners, but mine were well and truly seized up.
Once the frame is out, wind the window back up to get to the lock assembly. Mine sat quite comfortably on the regulator without support, but if the glass looks like it is going to fall out then remove it.
Disconnect the rod that runs from the inside door handle to the lock. There is a little split pin holding it on the lock, remove the pin and the rod will come off the lock. Keep the pin.
Undo the 3 phillips head scews on the door edge holding the lock. Undo the small nut holding the escutcheon plate in place. Remove the escutcheon plate.
You should now be able to remove the entire handle assembly through the cut out on the inside of the door. It takes a bit of manipulation. I found the easiest way was to move the handle to the open position, it seemed to help with the angles.
On the handle assembly, locate the locking barrel. On the side of the locking barrel you will find a locking pin that holds the barrel in the handle assembly. Using a suitable sized punch or nail, tap the pin through until it comes out the other side. The locking barrel will then fall out, or insert the key and use it to draw the locking barrel out.
Installation of the new lock is the reverse of the above. With more swearing. Give the lock assembly a squirt with WD40 or even better, a couple of puffs of graphite powder before you put it back in.
Try and avoid dropping stuff into the door, it's almost impossible to get out. I dropped both the quarter light spacers and a socket in there, they are now permanent residents.

I hope this helps. It's a bugger of a job.

Brilliant, thankyou very much Ferret I'll get round to doing that someday

Andy, bring the lock with you to the national and I'll talk you through it ;)
