Cost to Rekey Locks: What It Really Costs and When to Do It

When you move into a new home, lose a key, or want to stop someone from accessing your space, rekeying locks, the process of changing a lock’s internal pins so only a new key works. Also known as lock adjustment, it’s a quick, affordable fix that keeps your home secure without swapping out the whole lock. Many people assume they need to replace the entire lock mechanism—but that’s often unnecessary. Rekeying is cheaper, faster, and just as secure if done right.

So how much does it actually cost? In India, rekeying a single door lock usually runs between ₹800 and ₹2,500, depending on the lock type and location. In the UK, where locksmith salaries, the earnings of professionals who install, repair, and rekey locks. Also known as lock technicians, they earn between £25,000 and £45,000 a year, the cost per lock ranges from £40 to £100. The price varies based on the brand, complexity, and whether you need emergency service. A basic Yale lock is simple and cheap to rekey. A high-security deadbolt or smart lock? That’s more work, and it shows in the bill.

Why do people choose rekeying over replacement? It’s simple: you keep the same hardware, save money, and avoid the hassle of drilling out old locks or adjusting door frames. If your lock is still in good shape—no rust, no broken parts—rekeying makes perfect sense. But if the lock is old, damaged, or from a brand that’s no longer made, replacement might be the smarter long-term move. A good locksmith will tell you which option fits your situation.

And here’s something most people don’t think about: rekeying isn’t just for homes. Offices, rental units, hotels, and even vehicles use the same process. If you’re a landlord managing multiple properties, rekeying after each tenant moves out is a standard, cost-effective security practice. It’s not just about safety—it’s about control. You decide who has access, and you don’t have to carry a keyring full of old keys.

There’s also a skill gap here. Not everyone who claims to be a locksmith knows how to rekey properly. A bad job means your lock won’t turn smoothly, or worse—it could fail under pressure. That’s why you want someone trained, licensed, and experienced. In India, many vocational training institutes now offer short-term courses in lock repair and security systems, helping people turn this skill into a steady income. In fact, trade careers, hands-on jobs that require technical training rather than a university degree. Also known as skilled trades, they like plumbing, electrical work, and locksmithing are growing fast because they’re essential, hard to automate, and pay well without years of student debt.

So if you’re thinking about rekeying your locks, don’t just call the first handyman you find. Ask about their experience, get a written quote, and check if they use original manufacturer parts. And if you’re considering a career change—whether you’re 25 or 55—learning how to rekey locks could be one of the smartest moves you make. It’s a trade that never goes out of style, and demand keeps rising.
