Deadbolt & High-Security Lock Installation

Yes. Our mobile locksmith team operates 24 hours a day, seven days a week, including holidays. Whether you need an emergency deadbolt replacement after a break-in attempt on a Sunday night or a scheduled smart lock installation on a weekday afternoon, we dispatch a trained, insured technician to your Queens address. Call 718-568-8697 at any hour and a real person will answer.

New York City's Multiple Dwelling Law generally requires that entry doors in qualifying residential buildings be equipped with a deadbolt lock with a minimum one-inch throw bolt. The specific requirements depend on your building classification — Class A multiple dwellings have different obligations than Class B. Our technicians are familiar with these distinctions and can install hardware appropriate for your building type, helping you avoid HPD violations. We recommend bringing any existing violation notices to the appointment so we can confirm the correct hardware specification before installation.

In most cases, yes. Many smart lock models are designed to replace standard single-cylinder deadbolts directly, using the same door prep without any additional drilling. During the visit, our technician measures your existing prep, confirms compatibility, and proceeds with a damage-free installation where the door is already correctly prepped. If your door has a non-standard thickness or an older Euro-profile cylinder, we carry adapter hardware and can discuss the available options on the spot. We also verify that a physical key override remains functional after the smart lock is installed.

ANSI Grade 1 is the highest standard rating for residential and light commercial deadbolts, testing for kick resistance, cycle durability, and bolt strength. Most quality deadbolts from brands like Schlage or Kwikset at the Grade 1 level provide solid protection for typical residential use. High-security locks — such as those from Medeco or Mul-T-Lock — add restricted keyways that prevent unauthorized key duplication, hardened steel inserts that resist drilling, and anti-pick pin configurations. If you live in a building with a history of key duplication concerns, manage a business with sensitive inventory, or simply want the highest available level of protection, a high-security cylinder is worth the additional investment. Our technicians can walk you through the trade-offs during the estimate.

A straightforward deadbolt replacement on a prepped residential door — where no new boring is required — typically takes 30 to 60 minutes from the time our technician arrives. Adding a reinforced strike plate, door-frame armor, or a second lock on the same door adds time but usually keeps the total visit under 90 minutes. Smart lock installation takes a similar amount of time, with an additional 15 to 20 minutes for device pairing and app setup. Commercial installations involving mortise locks or access control hardware may take longer depending on the scope, and we will give you an accurate time estimate when you describe the job over the phone.

Yes, commercial keypad door lock installation is one of our most requested business services. Keypad and electronic access locks eliminate the need to rekey every time an employee leaves, allow you to set time-based access schedules, and generate an audit trail of who entered and when. We install standalone keypad deadbolts for smaller offices as well as networked access control readers for businesses that need centralized management across multiple entry points. Common requests come from retail shops, medical offices, warehouses, and restaurants throughout Queens — particularly businesses that need after-hours installation to avoid downtime. Call 718-568-8697 to describe your setup and we will recommend the appropriate hardware.
