Door Knob Lock & Deadbolt Rekey
When you move into a home near Green Bay Road or anywhere across Wilmette's tree-lined neighborhoods, you rarely know how many copies of your keys are floating around — with previous tenants, old neighbors, or contractors. That uncertainty alone is reason enough to schedule a door knob lock and deadbolt rekey before you unpack a single box. Smart Locksmith Service is a fully mobile, 24/7 locksmith team serving Wilmette, IL. Our trained and insured technicians come directly to your address, rekey your knob locks, deadbolts, and mortise lock hardware on the spot — no towing, no shop visit, no waiting.
Open 24 hours, 7 days a week · Licensed, bonded & insured
Losing a key or handing one off to someone you no longer trust raises the same concern: anyone holding that key can still walk through your front door. Rekeying is the most cost-effective and damage-free way to regain full control of your home's security without replacing the entire lockset. Whether you have a classic Kwikset knob lock, a Schlage deadbolt, a double lock door knob setup, or an older mortise lock on a vintage Wilmette bungalow, our technicians carry the tooling and replacement pins to rekey virtually any residential or commercial cylinder the same day you call.

Frequently asked questions
Answers to what our customers ask most. Still unsure? Just call.
How much does an emergency locksmith cost near me in Wilmette?+
The cost of an emergency locksmith visit in Wilmette depends on several factors: the type of lock or service needed (a standard knob lock rekey differs from a commercial mortise lock job), the time of day or night, how many cylinders are involved, whether replacement parts are required, and your specific location within the service area. Smart Locksmith Service always provides an exact, confirmed price before any work begins — there are no hidden charges added after the job is done. Call (224) 506-2454 to describe your situation and receive a clear quote.
How much is the average locksmith charge for rekeying a door knob lock and deadbolt?+
Average pricing varies widely because rekeying a single residential knob lock is a much smaller scope than rekeying a double lock door knob setup, a mortise lock, or an entire building's master key system. Additional variables include the lock brand, number of cylinders, whether you need same-day or after-hours service, and travel distance. Rather than publishing a number that may not apply to your specific locks, we confirm an exact up-front price once we assess your door hardware in person. Contact us at (224) 506-2454 to get started.
How long does it usually take for a locksmith to come to a Wilmette address?+
Response time depends on our current call volume and your specific location in Wilmette, but because Smart Locksmith Service operates as a fully mobile team — technicians are already on the road rather than waiting in a shop — we can often reach most Wilmette addresses relatively quickly after a call is confirmed. Once we have your address and job details, we give you a realistic arrival estimate. For urgent situations such as a lockout, call (224) 506-2454 directly so we can dispatch the nearest available technician immediately.
I heard someone can pick a door knob lock — should I be worried about my home's security?+
It is true that knob locks alone offer limited security because a standard door knob with lock is primarily a convenience latch, not a primary security device. Picking or bypassing a basic knob cylinder is not complicated for someone with the intent. That is exactly why security professionals recommend pairing every knob lock with a properly installed deadbolt — and ideally upgrading to a high-security cylinder or a smart lock door knob system that resists common bypass methods. If your Wilmette home relies on a knob lock alone, our trained technicians can assess your doors, upgrade your hardware, and ensure your deadbolt and knob lock are rekeyed to a single new key for maximum convenience and control.
What is the difference between rekeying and replacing a lock?+
Rekeying changes the internal pin tumblers of your existing cylinder so that the old key no longer works and a new key is issued. Your physical door knob with lock stays in place — only the internal code is altered. Replacing a lock means removing the entire lockset and installing new hardware. Rekeying is the right choice when your existing lock is in good working condition and you simply want to invalidate old keys — for example, after a move, a lost key, or an employee departure. Lock replacement makes more sense when the hardware is worn, damaged, or you want to upgrade to a higher-security mortise lock, smart lock, or heavy-duty commercial-grade cylinder. Our technicians will assess your situation and recommend the most appropriate option.
Can a locksmith program my key fob or smart lock door knob at my Wilmette home?+
Yes. Smart Locksmith Service provides key fob programming for most automotive makes and models, performed right at your Wilmette home or wherever your vehicle is located. We also install and set up smart lock door knob systems for residential and commercial properties — including keypad programming, app pairing guidance, and integration with existing deadbolts where applicable. If you are unsure whether your specific vehicle or smart lock model is compatible, call (224) 506-2454 and describe the make, model, and what you need — our team will confirm service availability before dispatching a technician.
