Hi. We have a 20 year old wired alarm system which works well but the Guardtec 550 keypad display is going. How easy is it for a competent DIYer to replace the control unit for one bought on line please? The alarm company want to charge £550 but you can buy a new alarm keypad online for less than £100. Many thanks in advance for any advice? Roger
