Hello and welcome to Thin Blue Locks.

I'm Charlotte, a female locksmith based in Bromley who is well equipped and experienced in dealing with lockouts, repairs, replacements, home security, crime prevention and much more to suit your needs. 

I am a full member of the UK Locksmith Association certifying me as a trained, qualified locksmith and fully police vetted. 

I created my company and learnt my trade after years of experience in a position where I saw the unfortunate repercussions of poor security. 

I have previously been working for a company and have gained enough experience now to start my own business. I’m new to check a trade hence the low numbers of customers etc. Please do not let this put you off.

My main goal is providing my customers with a safe and secure home to give them peace of mind. 

I provide the following services:

  •  Door Opening - after lock out.
  •  Lock Change.
  •  Lock Repair.
  •  UPVC Door Repair.
  •  UPVC Door Lock Change
  •  Security planning?
  •  Crime Prevention Advice
  •  Affordable Prices

Feel free to contact me for any enquiries and i'll be able to get straight back to you.
