Lockmaster Milamaster Centre Case. UPVC Door Lock Gearbox. 35mm Split Spindle

Installation was quick and straightforward. I also replaced the lock barrel and handles at the same time, and it all came together without any issues. It took me around 10 minutes to fit everything to the door, and the mechanism works smoothly.Very pleased with this purchase – a solid, reliable lock that’s easy to install and restores full function to the door.

Perfect fit, hopefully it lasts longer than the original part it replaced

I last bought this product in May 2018 and am replacing it again today. One of the cams broke into four pieces on the old one and it wasn't worth trying to source a spare when the new lock was less than £17. Even with next day postage it was still half the price of the closest supplier to me and it lasted 6 years so I think that represents reasonable serviceability from what is after all, a cheap lock. I think the open case design is not great as it allows debris and dirt easy access to the mechanism and I have had to grease it a couple of times over the years but for the price, it is still good value for money.

For the uPVC DIY’er or tradesman, this was a simple replacement that fits and matches the existing door lock.For the willing to give it a go DIY’er (like myself), do your homework first, and I’m not talking about the lock itself.Note what torx screws and bars come out of where, cause it matters when you put it all back together. Never taken the locks of myself, but thought while I had the whole mechanism including the upper and lower dead locks out, I thought I’d give them a clean. Stripped everything, cleaned all the dead locks and bars then put it back together when the new lock arrived. Did I not get the lower and upper bars that operate the dead locks round the wrong way🤦🏼‍♂️. I had the the whole lot in and out of the door more times than the number of years since door was fitted.Initially when the lock failed I panic bought an alternative suitable lock from Screwfix at £60 with next day collection, had a look on here and found this for next day delivery. Amazon delivered before Screwfix could and saved me two thirds of the price.The door now closes and locks like the day it was fitted, at this price it is well worth renewing if you are willing to have a go yourself, gonna get another for the front door now I know how easy it is.

This part replaced a Lockmaster lock in my UPVC door.Good as new.

The gearbox lasted 5 days... Now I'm locked out of my shed and something has snapped when locking the door.. absolute terrible.. who do I send the locksmith bill too?

Measure carefully to make sure you get the right match, but this is quite simple to replace and a damn-sight cheaper than replacing the whole door when the old lock mechanism started to wear out on my front door.

The product is exactly what was needed and does the job.I paid for same day delivery as offered. This was then changed to 3 days later, I then changed it to the following day which was accepted. The delivery never came. I tracked the package but "oops, we're running late" was all I got. So I called customer service to be told exactly what was on the website. Totally unhelpful! It finally arrived a week late!! Utterly awful delivery service and information distribution! We actually had to the part from a more reputable company! Not even an apology!
