People lose door keys for all sorts of reasons, rushing to work, juggling shopping, or dropping them somewhere on Oxford Street. The first reaction is nearly always stress, but forcing a door or “trying something” usually ends badly.
Once you’ve lost house keys or any other external door keys, remember:
Don’t try to force the lock to gain entry, you could break the keyway
Don’t climb through windows, injuries and insurance headaches follow
Do call a professional locksmith who can gain entry cleanly
As professional locksmiths, we’ll:
Get you back inside quickly, without damaging the door
Replace lost house keys or the full lock if needed
Make sure your property is fully secure again
People lose keys for the simplest reasons. Busy morning, wrong jacket, bag open on the bus, or they just fell out somewhere on Oxford Street. Happens to everyone.
Most people panic first, then get creative, try the windows, call a mate, maybe even Google “how to open a lock with a credit card.” Don’t. Just don’t. You’ll bend something or snap the latch and make the job harder later.
If your keys had your address on them, or anything that points back home, call us straight away, we’re professional locksmiths, we know the score. Better to get the locks changed and stop worrying.
If they were just a loose set, still best to get a new key and make sure your door’s properly secure.
At Mayfair Locksmith London, we handle it calmly. No damage, no judgement, just straight back in.
Sometimes it’s not just that the keys are gone. You start thinking about who’s got them, if they could gain access to your property, all that.
First thing, stay calm. Happens more than you think. Our locksmiths will get you sorted.
If there’s any chance that your missing keys are in fact stolen keys, or if you’ve had a break-in, then it’s not just about key replacement. You need those door locks (and window locks sometimes) changed, and quick. For obvious security reasons as well as insurance policy reasons.
We’ll pull the old lock cylinder, fit a solid new one, and check the door locks, hinges and frame while we’re there. If it’s a UPVC door, we’ll realign it too, no point having new locks if the door won’t close right.
You’ll have a fresh set of keys and your home security will be back where it should be.
Plenty of people ask if it’s fine just to get a replacement key cut. If you’ve genuinely misplaced the keys inside your home, maybe.
But if they vanished somewhere in the London area, you simply can’t know who has them now.
Changing the lock:
Restores full control of your home security
Keeps your insurance valid
Provides brand-new keys that only you possess
As professional locksmiths, we fit Yale, ERA, and Mul-T-Lock models, all British Standard and insurer-approved. We also work on all door types, including uPVC doors and windows.
If your insurance provider requests proof, we’ll issue documentation showing the locks were fitted by qualified, criminal-record-checked professionals.
Generally, it is not required to let your insurance provider know if you have lost the keys for your house.
But, if you have suffered a break in and you then need to a lock cylinder replacement, you would probably be best to let then know then.
You should also let your local police authority know, and, in the event it is security key, your security key provider.
Bit of advice — always check your home insurance when you lose keys (this applies to lost car keys as much as it does lost house keys or front door keys).
Some policies cover the lot: they’ll replace lost house keys, cover lock changes, and even call-out fees. Others, not so much. Depends on your insurance provider.
We’ve seen plenty of people pay out of pocket, only to find their insurance policy would have covered it if they’d called first.
If your insurer needs proof, we’ll sort it. We give written invoices showing which locks were fitted, who did the work, and that it’s all up to British Standard. Sometimes they’ll ask for the notable features of the locks — anti-snap, fire rated, that sort of thing — and we’ll note it down.
Main thing is, you stay secure and your paperwork’s clean. If you’re not sure, call them. Takes five minutes, saves hassle later.
Not every key’s the same, not every door’s the same either. Some old flats still use a mortice key, others a Yale night latch or newer window locks.
We’ve worked on all of them.
Lose the original key or the only set, and you’ve got two choices — we either make a replacement key, or we fit new locks that suit your front door better.
We’ll ask what kind of handle it’s got, if it’s a UPVC door or wooden one, that’s all we need to know before we come.
If you’ve got family members or tenants needing a spare set, we’ll cut extras while we’re there. All tested before we leave.
