UPVC doors, including those made with composites, need to be installed accurately for the locks to work correctly. Even tiny misalignments can mean one or more of the locking points around the door don’t slot into the bracket, and this is the most common reason to find your locks are sticking, stiff, or aren’t working at all.

The best advice is to contact an experienced locksmith right away, because UPVC doors, especially older models, are often fitted with standard euro-cylinder locks. These can be prone to lock snapping and may present a security risk for both domestic and commercial properties.

An experienced locksmith can assess the cause of the issue and recommend the fastest solution, whether fixing jammed locks, realigning the door, or changing the locks altogether.

Underlying Reasons UPVC Door Locks May Fail

Often installed as patio doors or within conservatories, UPVC doors are functional, affordable and durable. However, they’re also vulnerable to changes in temperatures, which means the door can expand in the heat, placing strain on the frame and locking mechanism, and contract in the winter.

In the latter scenario, you might find the handle feels stuck, but this is actually because the locking hooks can’t slot into the plates in the frame. 

UPVC locks are also intended to be maintained with regular lubrication, but often aren’t. This makes the lock stiffer over time and can mean you end up needing urgent UPVC door repairs in Coventry to ensure your home or business is secure.

Even if you’ve taken great care of your UPVC windows and doors, they’re heavy units, and if they’ve been installed for a few years, the door may sag or drop, causing the locking pins to fail to engage with their housings.

Whatever the reason, it’s strongly advisable to call a qualified locksmith, rather than trying to force a stiff handle or jimmy the door open. While that might enable you to access your property, it also means the cost of repairs will be higher.

Indications That a UPVC Door or Window Lock Is Approaching Failure

Ideally, you’ll be able to spot signs that your locks aren’t working as they should before a disaster occurs. It’s both quicker and cheaper to resolve an issue at the first indication of a problem with the lock rather than after it’s failed.

If any of the below sound familiar, we’d suggest you contact the Eydens team in Coventry:

  • The handle feels very stiff and jerky, or wobbly and loose
  • You’re able to ‘spin’ the key in the lock without it catching
  • You have to wrestle with the key and wiggle the door to get it to lock or unlock
  • The keys are difficult to remove or insert into the lock
  • You can hear crunching noises when turning the key or lifting the handle
  • Your door has visibly dropped or needs to be slammed or wriggled to close properly

Modern UPVC doors have gearboxes within the locking system, which might need to be replaced, but you could also require a simple door realignment, or, if the locks are about to fail, the lock itself could need to be upgraded, all of which a locksmith can tell you once they’ve assessed the door.

Secondary Problems With UPVC Doors 

Other issues that could indicate an inefficient UPVC door might not immediately affect the lock, but could point to a failure within your double glazing. If there is condensation inside the glass, with cloudy or misty windows, it’s well worth having this looked at because that dampness will inevitably reach the locking components sooner rather than later.

Likewise, if you can see a gap around the door frame or feel a draught, the door may not be closing properly and could be vulnerable to break-ins, while it’ll also be impacting your home’s energy efficiency, in which case double glazing repairs or a new front door may be advisable.

Advice on What to Do Following a Sudden Lock Breakage on a UPVC Door

We recognise that it can be enormously stressful to find that a door lock has broken, a key has snapped, or you can’t lock an entrance to your home or business. Customers who find themselves in this position and who have had a new door installed recently may be covered by their supplier’s guarantee or warranty period.

It’s worth checking this because if an installation error has caused the damage, you may be eligible to have it corrected or a new door fitted at no cost to you.

Otherwise, we’d suggest calling a locksmith right away if you cannot lock or unlock the door, because in an urgent situation where you need help to secure your home, an emergency locksmith callout is the best resolution. Depending on the problem, a locksmith might:

  • Realign the door there and then, our teams are fully insured and equipped with the tools they need to carry out a wide range of door and window repairs.
  • Open the door safely, without damaging the hinges or frame, and lubricate all parts of the lock and pins to ensure it works smoothly.
  • Adjust the door hinges and check that they are properly tightened if the issue is due to the door dropping.

In other scenarios, we might remove a broken lock, replace it with a high-quality alternative, and supply copies of the new keys, which you can pass to your household members to ensure everyone has access.

Eydens offers a 12-month guarantee on the complete door locking systems we supply, alongside fixed prices for UPVC door services (excluding emergency callouts), ensuring you know how much the repair will cost in advance.
