Many home insurance companies now require that all five lever locks are to be BS3621. This lock should be able to resist drilling and cutting using standard tools for five minutes and resist manipulation (lock picking).
All windows should have locking devices and new home owners must change the locks to their new property. If the property is entered by a previous owner who still has a key, or via a lost key, it could be classed as deception rather than theft and can make your insurance claim invalid.
Searching for local Locksmiths sometimes brings up national companies "pretending" to be local. These companies then pass the work onto Locksmiths, that can be many miles away from you and place a huge fee on top of the usual Locksmith rate. Such companies will take your card details before any work is carried out or even take payment if the work is cancelled.
NP Security Solutions are a family run Locksmith company based in Beccles and cover South Norfolk and Suffolk and we NEVER ask for payment up front. We will discuss works to be carried out, costs before starting and do not charge a call out fee.
Make sure the company you call is not a national company, adding unnecessary fees on top of a normal Locksmith rate.
If you ever attempt to fit your own locks as part of a DIY project, it is always important that the locks you fit to external doors are British Standard. It is often tempting to opt for a cheaper lock and with many DIY stores stocking internal 2 or 3 lever locks at good prices, it is easy get confused. The 2 or 3 lever locks are meant for internal doors and are seen as medium security. Many insurance companies will not see this as adequate security and this could harm any claims made.
So ensure any locks you buy for yourself are 5 lever mortice locks and not meant for bathroom use. Better still, call a Locksmith!
