Godrej is a top brand.And godrej produces the locks for home and industries with high security.We are using it for last 2years.And it comes with special pattern for each lock and key.And the key comes with special pattern.With this pattern, the lock is high secured.The main drawback with godrej locks is special key pattern.It is having desired pattern for each key.And we cannot make the duplicate keys.If the original keys were missed, there is no chance for duplicate keys.We must have to buy anew lock.I liked its high security but duplication is not possible.
