Are you available 24/7?

Most locksmiths accept card payments as well as cash. Ask when you book.

How quickly can a locksmith get to me?

It depends on where you are and the time of day. We'll give you an honest estimated arrival time when you call.

Non-destructive entry is always tried first. Drilling is a last resort and only done with your agreement.

It depends on the lock, the work and the time of day. Your locksmith will tell you the price before starting, and nothing goes ahead until you agree.

Will I need to prove I live there?

Many faults can be repaired. Your locksmith will explain the options and prices before doing any work.

Do you remove snapped keys?

Yes. Broken keys can usually be extracted without damaging the lock.

Why does my door only lock if I push it?

The door has usually dropped or swollen, so the bolt no longer lines up with the keep. Adjusting the hinges or keep usually solves it.

My uPVC handle won't lift. What's wrong?

It's usually a worn gearbox or a door that has dropped out of line. Both can usually be fixed.

Do I need a whole new door?

Almost never. The locking mechanism can be replaced without changing the door.

Can you fit it the same day?

Common mechanisms are often carried in the van. Less common ones may need ordering, and your door will be left secure in the meantime.

Why is my composite door harder to lock in summer?

Composite doors can expand in heat, which pushes the locking points out of line. Adjusting the keeps usually fixes it.

What's the difference between a deadlock and a sashlock?

A deadlock has a bolt only and is locked with a key. A sashlock adds a latch and handles, so the door can be closed without locking.

Is a Yale lock enough on my front door?

A basic nightlatch on its own usually isn't. Most insurers ask for a British Standard nightlatch or a BS3621 mortice deadlock as well.

Can all my doors use the same key?

Yes. Cylinders can be supplied keyed alike so one key opens every door.

How can I tell if my lock is anti-snap?

Look on the face of the cylinder for a kitemark with stars or a Sold Secure Diamond mark. If there's none, it's probably a standard cylinder.

Where do I find the BS3621 mark?

It's stamped on the lock's faceplate on the edge of the door, usually with a kitemark.

What's the single best upgrade?

For uPVC and composite doors, an anti-snap cylinder. For timber doors, a BS3621 mortice deadlock.

Should I call the police first?

Yes, if the break-in has just happened, call 999. Otherwise report it to 101 and get a crime reference number for your insurer. Then call us to secure the property.

Can you help with my insurance claim?

Your locksmith will provide an invoice detailing the work, which you can give to your insurer.

Can you work outside our opening hours?

Yes. Tell us when suits you and we'll arrange a locksmith around it.

Can the locksmith meet my tenant?

Yes. Give us the tenant's contact details and we'll arrange access with them.

Can you fit an extra lock to my garage door?

Yes. Adding a second lock is one of the most effective ways to secure a garage.
