New house new locks

When you get the keys to your new house you really should consider changing the locks. You just change the barrels. Some people might think it’s an unneccessary expense but it’s not hugely expensive and will give you instant peace of mind.
If you’ve never done it before then watch some videos or ask for help!
Take the details of the locks (with photos on your phone and measurements of lock height and distance of key hole from edge of door) to a diy shop and ask for assistance in buying new locks.
Locksmiths will do it for you but will cost more!
