You may need to change your locks, whether it is an emergency or if you have recently moved house, or just want to upgrade to the current British Standard BS3621. AP Higgs Locksmiths offers both an emergency service and the option to book an appointment that best suits you. Our locksmiths are fully trained and trustworthy and as part of a lock change service we can carry out a free home security check. Reasons to change a lock: If you have been burgled. If you have moved house. If you lose your keys or they are stolen. If your lock is broken or unreliable. If you don’t know how many people have a spare key. If you are a landlord and tenants have moved on. If your locks do not conform to BS3621. We cover Cardiff, Newport, Caerphilly, Pontypridd, Llantrisant, Penarth, Cwmbran, Chepstow and Barry.
