We had a key had become stuck in the lock and could not be pulled out.   Banham told us it would be £117.60 for the removal of the key and a service.   The 4 screws on the lock are old and have become worn.   We asked the technician to change the screws after he had finished his 15 minutes service, and he said they were like that, became very defensive and said he didn’t have the screws with him. We also pointed out that 1 screw wasn’t even screwed in properly, it was sticking out, his response to this was: “I don’t want to tighten it too much”. However it wasn’t even screwed in properly, so it wasn’t a case of “tightening it too much”.   As part of the job of removing the key and servicing the lock, he had to unscrew the screws. It would then make sense for the technician to carry some spare screws. e.g. if one was damaged or lost during the service. Anyone screwing and unscrewing these screws would only add to the wear and tear on the screws. I then phoned Banham to ask for the technician to come to replace the screws, the service assistant said it would be £2 pounds per screw plus VAT !   It would make sense for replacement screws to be offered as part of the £117,60 service charge. Banham Is the manufacturer of the lock, is the only company who have service my lock, they don’t replace screws ! Technicians don’t carry screws in their van, they said it is very rare to have to replace screws, they charge £117,60 for a call out and can’t replace 1 or 2 screws ! This is my last lock from Banham.
