If a lock has been damaged to an extent where repairing the lock seems impossible then only a lock should be changed and a brand-new advanced lock can be installed in place of the older obsolete one. Technicians know exactly what points are needed to pass or fail the security test of a lock. If your lock passes the test, you may keep using it but if GO Locksmith’s technician asks you to replace the lock, it is the best for your security.
