Keep the useful hardware, when suitable.
Tell us how many locks you want considered and whether the same key currently opens them. The hardware needs to be checked before promising that several doors can share one new key.
A worn cylinder or a door that does not latch may need a different solution. Describe those symptoms using our lock repair page, and keep garage controls on a separate home-access checklist.
A spare key is useful information.
Tell us whether a working key is available and which doors it opens now. If different locks already use different keys, mention that before asking about a shared key. Suitability and compatibility need to be assessed rather than assumed.
For a home around Grand Peninsula or elsewhere in Grand Prairie, count the actual locks rather than only the number of outside doors. A door can have more than one keyed lock. Our estimate questions help you discuss the proposed work clearly.
