UPVC door locking mechanism problems

UPVC door locking mechanism problems can be an issue without proper care. With an expected lifespan of 20 years, UPVC windows and doors are a popular choice for homeowners. But, when your UPVC door won’t lock, or can’t be unlocked, it can be a threat to household security.

Thankfully, many of these problems can be solved with a quick fix. From regular maintenance and TLC through to replacing parts and testing for weaknesses, let’s take a look at some of the most common UPVC door issues.

UPVC door won’t lock

If your UPVC door won’t lock, it may be because your locks are misaligned. This can be caused by hot weather causing the door to warp. Additionally, wear and tear accumulated over the years can cause the door to ‘drop,’ meaning the door no longer fits with the lock.

By using a screwdriver on the inside of the doorframe, you can loosen the door from the frame. Doing so may get the door to align again with the lock. Be warned – this may involve a bit of trial and error!

If you’re unsure if your locks are misaligned, there’s an easy way to check. Try locking and unlocking the door when it is not in the frame. If it all works perfectly, it may be there’s no problem with the mechanism and your locks are misaligned. If it doesn’t, you’ll need to look into getting the lock replaced. 

UPVC door lock mechanism sticking

Another common issue with these doors is the UPVC door lock mechanism sticking. This can even get to a point where the UPVC door handle won’t lift to lock. This can be caused by a build-up of dirt and debris in the lock mechanism.

Stiff locks can be treated with a light coating of oil  – such as sewing machine oil, not WD40  – or graphite powder to lubricate the mechanism.

UPVC locks work on a gearbox system. If they don’t respond to any treatment, it could be that the gearbox has failed, and needs replacing. Thankfully, this is quite easily done, as it is not the entire mechanism.

UPVC door lock broken

Over time, pressure on locks can cause them to break. Good maintenance can relieve some of the pressure and keep your locks in good condition for longer.

There’s also no substitute for TLC – being gentle on the mechanism when you raise the handle relieves pressure, and helps your locks last for longer.

UPVC door exploitable locks

Unfortunately, locks that come with UPVC doors are often quite easily picked and broken. This is a serious concern for homeowners – in 2021, 258,185 burglaries were reported across the UK.

There isn’t a simple fix for a bad lock. You can add additional bolts and chains, but this may make your new door less aesthetically pleasing. The best solution to a subpar lock is to replace it altogether.

At The York Locksmith Company, we can fit Anti-Snap locks. These deter burglars as it makes one of the easiest ways burglars get in (snapping the lock) considerably tougher.

How much will this cost? It depends, but typically the parts for a good quality anti-snap lock will cost around £50, and a typical weekday callout will cost £80. A good investment, when you consider what’s at stake – keeping opportunists out of your home!

Safety first

UPVC doors can be a great low-maintenance option to protect your home, but they need as much care and attention as any other lock. Contact The York Locksmith Company today for expert advice on fixing common UPVC door locking mechanism problems.
