Frequently asked questions
Answers to what our customers ask most. Still unsure? Just call.
How quickly can you get to my business in Tooting for a commercial lock change?+
We send a technician out straight away when you call, and we are usually on site in around 30 minutes for addresses across the SW17 area. That said, we ask you not to treat it as a guaranteed arrival time — traffic on routes such as the A24 through Tooting can vary, particularly during the morning and evening peaks. We will give you a realistic expectation when you call 020 3675 7793, and you can reach us at any hour, including weekends and bank holidays.
Does changing the lock mean the door or frame will be damaged?+
In the vast majority of commercial jobs, a lock change — particularly a euro cylinder swap — requires no drilling or cutting and leaves the door and frame intact. Where the existing lock case needs to be changed for a different size or type, some work to the door face may be necessary, but our technicians are trained to keep any impact to the door to an absolute minimum and will explain what is involved before they start. If there is any existing damage from a previous break-in or a failed entry attempt, we will assess that separately and explain your options.
What factors affect the cost of a commercial lock change?+
The price depends on a few straightforward things: the type and security rating of the lock or cylinder needed, the number of doors being worked on, the time of day (evening, overnight, and bank holiday attendances carry a higher rate than standard daytime hours), and travel distance if your premises is at the edge of our coverage area. We confirm an exact figure on the phone before any technician sets off, so there are no surprises when the invoice is raised. We do not add charges mid-job without your agreement.
My premises has uPVC doors with multipoint locks — can you change those?+
Yes. uPVC commercial doors with multipoint locking mechanisms are one of the most common jobs we handle in Tooting. The euro cylinder within a multipoint lock can usually be swapped without replacing the entire mechanism, and upgrading to an anti-snap, TS007-rated cylinder on these doors is straightforward. If the multipoint mechanism itself has failed or is damaged, we carry replacement gearboxes for the most common profiles. We will confirm on the phone whether we are likely to have the right parts before we come out.
A member of staff left last week and may still have a key — do I need to change every lock?+
You need to change the cylinder on every door that the former keyholder had access to. If they had a single key to the main entrance only, that is usually one cylinder. If they held a key to a back door, a storeroom, or any secondary entrance, those cylinders should be changed at the same time. It is tempting to change only the front door to keep the cost down, but any door left on the original cylinder remains a risk. We can work through all affected doors in a single visit and will tell you on the phone what to expect in terms of time and cost before we come out.
Can you match the new keys so that one key opens multiple locks on my premises?+
We can fit cylinders from the same range so that a small number of master-keyed locks operate on a single key — this is sometimes called a master key suite. However, full master key systems for larger commercial premises are a specialist supply-and-install service that goes beyond what a standard mobile lock change covers, and we will tell you honestly if your requirements need that level of system design. For most small offices and shops in Tooting, fitting two or three matching cylinders from the same manufacturer's range is entirely achievable on the day, and we will advise you on the best approach when you call 020 3675 7793.
