Our history

The branch was first established in 1961 by Mr Denis Jones, as "D.H. Jones Master Locksmiths".

In 1989 the business was sold and renamed to "Southern Stronghold t/a D.H. Jones Master Locksmiths", until it was acquired in 2022 by Croma Locksmiths.

All of our staff are fully trained locksmiths, and we continue to supply Coventry, and surrounding areas, with quality security solutions and products.

We are able to advise over the phone or in the branch as to the best products for your application. We display stock in our branch at 8 Cedars Avenue, and we can source items on next day delivery.

We invite you to visit our branch at 8 Cedars Avenue, and we would be happy to assist you with any requirement.

Highly recommended fitting staff

Peter Warrilow

Really excellent service. My double glazed door mechanism broke needed a complete new locking mechanism. I phoned on a Friday, they arrived with an hour and made the door secure, ordered the replacement and returned on the Monday to fit
