Frequently asked questions
Short answers for common deadbolt service questions before you request help.
When should a deadbolt be replaced instead of repaired?
Replacement is usually better when the lock body, bolt or internal parts are worn, damaged or unreliable.
Can the new deadbolt use the same key?
Often, yes, if the replacement deadbolt can be set up to match the existing keying. We check this before confirming the replacement lock.
Can you replace a deadbolt without changing the door handle?
Yes, if the handle set is separate and still suitable. We can replace only the deadbolt where the door setup allows it.
