Got hold of the company that produce the alarm systems for CTR's (Hamilton & Palmer)
They do refurb kits for the Preface & face lift fob.
Includes:
2 plastics
New buttons
3 screws
Battery
All for the price of £12.00. This should be the same price for both style fobs.
The contact details for the person I was speaking with at the company is:
