When to change or upgrade a lock

  • New home or lost keys

    You do not know who holds keys, keys are lost or stolen, or a tenant has left.

  • Insurance and anti-snap

    BS 3621 mortice locks for timber doors, and TS 007 anti-snap cylinders for uPVC and composite doors.

  • A stiff or worn lock

    Mortice locks, rim locks and nightlatches repaired, or replaced before they fail.

Many home insurers ask for a BS 3621 lock on final exit doors. Look for the Kitemark and “BS 3621” stamped on the metal plate on the door edge.

  • We rang Power Lock & Security when we discovered that we had lost both keys for our summerhouse. Their communications were excellent. They arrived at the agreed time and within 15 minutes the door had been opened the lock changed, and we were presented with 5 keys. If you want speedy service and quality work, look no further.

  • I absolutely recommend Power Lock & Security. Liam provided a great service, took the time and extra care to make sure our new door buzzer worked properly whilst ensuring we were happy with the buzzer and handset speaker volume at both ends. 5 stars!

  • Called Liam in the morning after our door wouldn't lock. He was great and popped round in the afternoon. 10-15 mins later we managed to lock our door. Liam was polite, responsive, good value and did a great job. Will def use again and would absolutely recommend. Thanks so much.

  • I can highly recommend this company for being knowledgeable, responsive, professional and trustworthy. Liam was extremely skilful at identifying the problem on our tenement intercom speaker system (which we thought may be beyond repair). He was able to source a replacement part and fixed it swiftly. He also repaired the main door lock which had been broken. Other companies only wanted to install a whole new expensive intercom system without actually working out what the problem was. Liam communicated clearly and promptly every step of the way and made it straightforward. Excellent and high quality service. I will be recommending and using this company again.

  • Liam was recommended by XS Locksmiths on Easter Road and I couldn't have been happier with the service! He was easy to reach on the phone and answered all my questions straight away. He was available within days, showed up on time and fitted our new Yale lock in half an hour. Very friendly & high-quality service. Definitely recommend!

  • From changing locks, getting new handles, making internal doors easier to close, and sorting issues with sticky tilt and turn windows, Power Lock & Security was great to deal with. Prompt responses, good advice, speedy and high quality work.

  • We were referred to PLS by XS Locksmiths on Easter Road. We needed our internal flat handset fixed (was totally fuzzy/we couldn't hear or speak through it). Liam was super easy to deal with, clear comms via email about dates and times to come out and fix.

    He was also masked up for anyone concerned about distancing/masks etc! Plus he helped with the loose maindoor lock as well when he was here.

    We'll defo use again for any lock issues in future and will recommend to others. Thank you!

FAQs

Common questions

Need help now? Phone 0131 358 9585.

Do I need a BS 3621 lock for my home insurance?

Many policies ask for a BS 3621 lock, or one of equal standard, on final exit doors. Check your policy wording. Our guide explains what the standard means.

Can you change only the cylinder on a uPVC door?

Yes. On most uPVC and composite doors the euro cylinder can be changed without touching the multipoint lock. We measure it so the new cylinder sits flush with the handle.

Can several locks work on one key?

Yes. Cylinders can be supplied keyed alike, so one key opens the front door, the back door and the shed.

Can you cut spare keys?

Yes, for many common keys. Some high-security keys can only be cut by the maker, on proof that you own the lock.

Need a lock changed?

Phone us with the door and the lock, and we will tell you the price.
