Standing on your front porch in Arlington Heights at 11 p.m., digging through your bag for a key that isn't there — it's a situation that happens to careful, responsible homeowners all the time. The good news: a skilled locksmith can almost always open a residential door without leaving a scratch, a splinter, or a bent frame behind. The method depends on your specific lock type, and the process starts long before any tool comes out of the bag.
At Arlington Heights Locksmith, we run a 24/7 mobile operation serving the greater Arlington Heights, IL area — from the neighborhoods near Frontier Park to the streets flanking Campbell Street downtown. This article walks you through exactly how we verify you belong at the door, which non-destructive techniques apply to common lock types (including the mortise lock), and what you can do right now to make a future lockout faster and less stressful.
Frequently asked questions
Can a locksmith open a deadbolt or mortise lock without drilling?+
In the vast majority of residential situations, yes. A trained locksmith uses non-destructive techniques tailored to the specific lock — whether that's a standard deadbolt, a knob lock, or a mortise lock. Drilling is a genuine last resort used only when a lock is mechanically damaged, severely corroded, or the homeowner is replacing it anyway. We always explain the approach and the reason before any work begins.
What is the average call out fee for a locksmith, and what affects the final price?+
There's no single flat figure that applies to every situation — and any company that quotes a rock-bottom price over the phone without knowing your lock type, location, and time of call should be a caution sign. The factors that determine a legitimate quote include the type of lock or vehicle involved, the time of day (overnight and holiday calls reflect real operational costs), travel distance to your location, and whether any parts need to be replaced. At Arlington Heights Locksmith, we confirm an exact up-front price with you before any work starts, so there are no surprises when the job is done.
How do I change the code on my door lock if I've forgotten the programming code?+
The answer depends on the lock brand and model. For most Schlage and Kwikset keypad locks, there's a reset procedure that restores factory defaults, after which you can set a new user code. The catch is that you typically need the original programming or master code to add new codes without a full reset. If that code is lost, a professional locksmith can often help you work through the reset process and reconfigure the lock — including setting up new codes and disabling old ones. If you're in that situation, give us a call and we can walk through it with you.
What locks can locksmiths not open, and when is damage unavoidable?+
Very high-security locks — certain grade-1 commercial cylinders, high-security padlocks with anti-pick pins, and some biometric systems — can be extremely difficult or time-prohibitive to open non-destructively. In those cases, drilling or cutting may be the only practical option, and a professional will tell you that honestly before proceeding rather than attempting a technique that damages the door unnecessarily. For standard residential hardware, including mortise locks and common deadbolts, non-destructive entry is the norm, not the exception.
