If you’re a homeowner, landlord, or tenant in the UK, you’ve likely heard of “British Standard” locks — and particularly BS3621. But what exactly does that mean? And why does it matter?
At RJ Parker Locksmiths, we regularly help customers who are either upgrading their home security or making sure their locks comply with insurance requirements. In this blog, we’ll explain what BS3621 is, why it’s important, and how to tell if your locks are compliant.

Losing your car key can be stressful — especially if you don’t have a spare. But don’t panic just yet. One of the most common questions we get asked at Parker Auto Locksmiths is: Can you replace a car key without the original? The good news is — yes, we can.

As summer temperatures rise in the UK, many homeowners welcome the sunshine—but overlook how the heat can impact their property. One often-forgotten victim of warmer weather is the humble door. Hot weather can cause swelling, warping, and misalignment, which can lead to lock issues, sticking doors, or even security failures.

With UK summers getting warmer, it’s not just us humans feeling the heat—your car keys are too. Whether you’re heading off on a road trip, parking up at the beach, or simply commuting to work, the last thing you want is your car key failing when you need it most.
At Parker Auto Locksmiths, we’ve seen a rise in summer-related callouts, many of which are due to weather-related issues affecting modern car keys. In this blog, we’ll explain why car keys can fail in hot weather, what you can do to prevent it, and when to call an expert for help.

With summer in full swing, many of us are enjoying more time in the garden, hosting barbecues, and opening up our homes to let in the fresh air. Patio doors—whether they’re sliding, French, or bi-fold—get a lot of use during the warmer months. But while they offer convenience and a great connection between indoor and outdoor living spaces, they can also present a potential weak point in your home’s security.
In this blog, we’ll explore how to check if your patio door locks are up to standard, what to look for when assessing their condition, and what steps you can take this summer to ensure your property remains secure.
