High-Security Patented Keyway Locks

Locks like Medeco, Abloy, and Mul-T-Lock are built specifically to resist picking and bumping — that’s the entire point of the product, and it’s a legitimate security feature, not a flaw. A locksmith without the specific tooling or training for that particular patented system may not be able to pick it open non-destructively, even though the same locksmith could pick a standard pin-tumbler lock in minutes. The honest path here is usually drilling (which destroys the cylinder and requires a replacement) or, if you have any documentation, contacting the manufacturer or original installer directly.

Certain Electronic and Smart Locks

A smart lock that’s out of battery, has a corrupted firmware update, or uses a proprietary app-based system can sometimes be more difficult to get into than a purely mechanical lock — there’s often no traditional keyway to pick at all. Depending on the brand, the real fix may be a manufacturer reset procedure, a physical key override (if the model has one), or in some cases contacting the manufacturer’s support line directly, rather than anything a locksmith can do on-site.

Safes With No Known Combination

Opening a safe non-destructively generally requires either the combination, a factory reset code tied to the safe’s serial number, or manipulation skills specific to that lock type — and not every locksmith carries safe-specific expertise, since it’s often treated as its own specialty within the trade. A safe with a damaged lock, a lost combination, and no accessible serial number may ultimately require drilling, which a general locksmith may or may not be equipped to do depending on the safe’s construction.

Some Late-Model Vehicle Immobilizer Systems

Most vehicles can be keyed and programmed by a qualified mobile locksmith, but a small number of newer vehicles use proprietary security systems that only dealer-level equipment can access — this is the honest exception mentioned on our automotive locksmith page. We’ll tell you upfront if your vehicle falls into that category rather than attempting a job that isn’t going to work.

What “Can’t Open” Actually Means

It’s worth separating two different questions: can a lock be opened at all, versus can it be opened without damaging it. Almost any lock can eventually be opened through destructive methods — drilling, cutting, or forcing. What a locksmith genuinely can’t always do is open a high-security or proprietary lock without damaging it, which is why “high security, has to be drilled” should be backed up by an honest explanation of which specific lock feature makes that true, not used as a vague excuse to justify a bigger bill. See our guide on how to tell a fair invoice from an overcharge if a “can’t be picked, must be drilled” claim doesn’t sit right with you.

What Locks Can Locksmiths Not Open? Questions, Answered Directly

Can a Locksmith Open Any Lock Given Enough Time?

Not necessarily without damaging it. Some patented high-security locks are specifically engineered to resist picking and bumping regardless of how much time is spent, which is why drilling — not more time — is often the realistic path for those specific locks.

Is It a Red Flag If a Locksmith Says They Can’t Pick a Lock?

Not by itself — some locks genuinely can’t be picked without the right specialized tools, and an honest locksmith telling you that upfront is a good sign, not a bad one. The red flag isn’t the claim itself, it’s an unexplained jump straight to the most expensive option without telling you why.

What Should I Do If My Smart Lock Won’t Open and a Locksmith Can’t Help?

Check the manufacturer’s support resources first for a reset or override procedure specific to your model, since many smart lock issues are firmware or battery related rather than a physical lock problem a locksmith’s tools can address. If it turns out to be a genuine mechanical failure, a locksmith can typically still help with the physical hardware once the electronic issue is ruled out.
