After finally buying our own home, I knew that safety and security was key. I looked at various products on multiple sites and then I cane accross safe ( : . This site is by far the easiest site I looked at when selecting all of the particular specifications for the lock I needed. I loved the fact I could order extra keys, although I did get confused as to how many I was buying. But much to my suprise I was phoned by a member of the fantastic team to discuss the amount of keys I had ordered and they quickly sorted the correct amount and refunded me. Excellent service I would definitely recommend safe to anyone who wants great service and high quality products ( :

Can two locks with different sizes have key-alike?
