Deadbolt Installation

A single-cylinder deadbolt is the most common choice for exterior residential doors. It uses a key on the outside and a thumb-turn on the inside, making it fast to operate in an emergency exit situation. For most Queens homeowners with solid wood or steel exterior doors — the kind you see running up and down the attached two-family homes in Woodside or Richmond Hill — a properly installed single-cylinder deadbolt with a reinforced strike plate delivers strong, code-compliant protection without complicating your daily routine.

A double-cylinder deadbolt, by contrast, requires a key on both sides. This configuration is particularly useful when a door has a glass panel or sidelight close enough to the lock that a burglar could reach through and turn a thumb-turn. The trade-off is egress speed in a fire, so local building considerations matter. Our technicians evaluate your specific door geometry, glass proximity, and household situation before recommending a double-cylinder model, and we walk you through the safety implications honestly. We never upsell hardware that does not serve your actual needs.

No honest locksmith can quote a single flat number without seeing the door, and anyone who does should raise a flag. Several real variables affect your final cost: the type of lock being installed (a standard single-cylinder deadbolt versus a mortise lock or high-security model like a Schlage B-series), whether your door requires drilling a new bore hole or if an existing bore needs to be enlarged, the condition of the door frame and whether a reinforced strike plate or additional hardware is needed, the time of day the work is performed, and travel distance within Queens. Emergency locksmith calls outside of standard business hours may carry a different service fee than a scheduled daytime appointment.

What we guarantee is this: before any work begins, you will receive an exact up-front price confirmed verbally. There are no hidden add-ons after the job is done. If additional parts are required — say, a longer strike plate because your door frame has shifted over the years — we tell you the cost before we install it. That transparency is simply how we operate. For a precise quote on your specific door, contact us at 718-689-7019 any time, day or night.

Queens is a borough of neighborhoods that each run on their own rhythm — the produce markets on Main Street Flushing close late, the bars in Astoria go past midnight, and plenty of residents on the A train corridor in Howard Beach work overnight shifts. A lockout or a broken lock does not wait for business hours, which is why Bay Terrace Locksmith maintains 24/7 availability every day of the year, including holidays. Our mobile technicians are already positioned throughout Queens, which means realistic arrival times rather than promises we cannot keep.

If you are locked out and wondering whether to try a window or a back door first, the safest steps are always to check for a spare key with a trusted neighbor, contact your building super if you are in an apartment, and verify all other legitimate entry points before calling us. Once you call 718-689-7019, we dispatch immediately and confirm an estimated arrival window before we hang up. For scheduled appointments — upgrading your locks after a move to a new place in Elmhurst, for example, or adding a deadbolt to a basement door — we work around your availability, including evenings and weekends.
