Common Double Glazing front door lock problems

This sounds strange but I have come across a few UPVC and Composite front doors lately that can be opened with just the outside handle when not fully locked (fully locked = lift handle plus turn key)

Of Course a front door should not be able to be opened from the outside without a key. Furthermore if your front door does open with just the outside handle then you may have a back/porch door style lock fitted inside your front door (fairly common) or the correct fittings have not been fitted inside your handles (also fairly common) or your locking system could be part broken.

Also I have noticed that a lot of UPVC, composite and aluminium doors spring back open when you shut them, I can also fix this problem (some people just lift the handle to hold the door shut but this will cause excess ware on the handle and locking mechanism). In addition click here for our composite door services.

Why has my door lock stopped working?

Is your front or back door difficult to operate and requires extra force to lift the handle or lock? The most common cause for the lock to break or fail, would be if the door was out of alignment.  With David’s expertise and knowledge, he specializes in technical door alignments.  Most Locksmiths do not carry out door alignment checks when they renew locks. Many Locksmiths tell customers that if they have a problem lifting the door handles, this is due to a faulty locking mechanism but this is not always the case. Stiff or notches handles are more likely due to bad door misalignment. So customers might not require a new lock, just a door adjustment.

How we can help you?

A customer recently contacted us as she was having trouble with her back door lock which had jammed shut. The homeowner had previously spoken to a Locksmith who had stated he could not open the door without possibly damaging the plastic door or frame. Many people posing as Locksmith’s have minimal training and skill. David has the skills and knowledge to successfully open your jammed shut doors without damage. A new multi-lock is not always necessary as the lock can be repaired and a less expensive option for our customers. If David is unable to open the door, then the customer will not be charged any fees. We inform all our customers during our telephone call or online communications of our fixed costs to open your jammed doors, repair your door locks or replace your multi-point door lock.

I do not know the age or manufacturer of my door, can you still help?

Don’t worry if your door lock or door handles does not have any manufacturers markings or names as many don’t. We will be able to identify your lock or handles and offer a repair or replacement. Even if your door lock is very old and discontinued, we can offer a conversion to a more modern door locking system. With every lock repair or replacement we carry out we always check and align the door and make sure that the door locks smoothly and correctly.

Door lock repair service for upvc doors Bexleyheath

How to test if the door lock (lift lever type) is the problem or the door alignment is the problem:
  1. With the door open try to lift the handles and turn the key. Furthermore if this works, your lock is in working order. Therefore your door will only require a re-alignment to fix the issue.
  2. In addition if your handle will lift with the door open but the key won’t turn. Consequently it is most likely to be a cylinder / barrel issue but could also be a multi lock problem.
  3. However, if your handles won’t lift with the door open? Then it is most likely a lock problem

Different styles of front door locks:

Please be aware that most front door locks operate differently to back door, porch door, French door, patio door and tilt and slide door locks.

Different styles of Front Door Locks:

  1. Front door lock with the handles at the same level, hence these types of locks use a split spindle to allow the inner and outer handles to operate differently.
  2. Front door lock with an outside handle lower than the inside handle, these lock using a twin spindle system to allow the inner and outer handles to operate separately.
  3. Front door lock with a fixed outer handle and push down inner lever handle. These older style locks allow the inner handle to open the latch part of the lock and therefore require a key on the outside to fully lock and open the door.
  4. Fixed inner and outer handle, this type of older style locks only operate with the key from both sides.
  5. Front door locks that have lift handles on both sides of the door but allow the outside handle to open the door, this is incorrect for a front door and either not installed correctly or the wrong model of lock for a front door.
  6. Customers with front door locks with lift handles on both sides but automatically fully locks when lifting a handle, these locks are called auto locks which always require a key to unlock them after lifting the handle.

Common faults with double glazed door locks:
  1. My front door key won’t turn? This is because either a damaged key, faulty cylinder, dropped door or faulty multi point lock.
  2. The key turns but the handles will not move?  Your cause of the problem, maybe due to a jammed multi lock.
  3. My key turns and the handles spin but the door will not open? The customer may have either faulty handles or a broken locking system.
  4. The door handles will not lift when the door is closed? This is a result of a dropped door or a lock problem.
  5. Why are my door handles really stiff to lift? The most likely cause would be a misaligned door.
  6. My front door latch can be opened using the outside handle without the need for a key? Call now for a chat to discuss the door problem further.
  7. I can’t remove my key when the door is locked? Please call for a free quotation.
  8. My door bounces back open when I close it unless I lift the handle to keep it shut?  This could be due to either the latch part of the lock not working or the door is misaligned.
  9. The door key is stiff to turn or difficult to insert into the lock barrel? A common cause for this problem is lack of lubrication. Customers can try applying a little oil on the key and working in and out of the cylinder. If the key is still tight then the barrel or key might be worn or damaged and need replacing.
  10. My door handles are loose, wobbly, floppy, stiff, notchy or broken off? This maybe either lack of lubrication, worn handles, broken springs, faulty lock etc. all fixable.
