Somsec Security
Our team have over 25 years of experience in the locksmith and security industry. We are a family run business, established in 2003.
We started by offering key cutting services and lock changes but have since expanded to include a full range of home and commercial property security solutions. These include the installation of new front doors and bespoke door frames. We are known in the area for our friendliness and our willingness to help.
Get in touch with us, we will be happy to discuss any security needs you may have.


WHY CHOOSE US?
Somsec Security are a real bricks and mortar shop on the high street. We are not a call centre and we do not operate from a van. That means that you always know where to find us and you can meet us face-to-face. This gives you the security of knowing that the person you are allowing into your house has the same ties to your community as you do.
​
Our engineers have been with us for years and have been personally vetted by us. As a family owned and run business, we care deeply about our reputation and are committed to providing a quality service at a fair price.

"Under Lock and Key were amazing. We just bought a new house. They gave loads of advice about how to change the locks for the most cost effective way ( thanks Toni) and when the change didn’t go to plan (the existing lock was too far gone) - they ordered the part super quick and didn’t need even charge for the second call out charge. Would totally recommend!"

"Great service from the team. The whole process was simple - easy to book a time for Jack the locksmith to drop by our house and the work of changing locks was done very efficiently at a good price. Jack is a good guy and gave solid advice on how to maximise security while he carried out the work - fully recommend the Under Lock and Key team."
Amrit
Super helpful and knowledgeable. Had a whole door replaced as well as locks after we moved house. Really happy with the quality of work and the guidance we were offered.
