What a unicorn! I needed new keys cut to fit a classic motorcycle ignition barrel without the original key to work off. He found new key blanks to fit, pulled the barrel apart and cut new keys to fit all within 2 days. Fast, quality work and service, and cheap. What a unicorn.

The team at Top Lock Locksmiths were prompt and the only ones to respond to my online query during lockdown. I recently moved into a new property where the previous owners didnt leave keys for a couple of locks. After a quick email exchange and online quote, Top Lock were able to send someone to replace a lock and cut some keys. The team were professional and efficient. Would definitely use Top Lock Locksmiths again.
