If you’ve lost your car keys or you’re worried about someone else having a copy, you might be wondering: Should I get my car lock rekeyed or replaced? If you’re in Detroit and trying to figure out the cheapest way to secure your vehicle, you’re not alone. This is a common question we hear at Locksmiths of Detroit, and it’s a smart one to ask.
In this guide, we’ll break down the key differences between rekeying and replacing your car locks, how much they typically cost in Detroit, when you should choose one over the other, and how to make the most cost-effective decision for your situation.
Let’s take the mystery out of this decision and help you feel confident moving forward.
What’s the Difference Between Rekeying and Replacing a Car Lock?
Before we crunch the numbers, let’s make sure we’re on the same page.
What Is Rekeying a Car Lock?
Rekeying means changing the internal components of the lock—usually the lock pins—so that only a new key will operate it. The structure of the lock stays the same; it’s just modified to work with a different key.
Key points about rekeying:
- You keep the existing lock hardware.
- Only the key changes.
- It’s usually quicker than full replacement.
- Often cheaper than replacement.
What Is Replacing a Car Lock?
Replacing involves removing and swapping out the entire lock mechanism. That means installing a brand-new lock cylinder that uses a new key.
Key points about lock replacement:
- The entire lock is swapped.
- Useful if the lock is damaged, worn out, or outdated.
- Often more expensive due to parts and labor.
- May require programming if it’s a modern electronic system.
Which Option Is Cheaper in Detroit?
Let’s get specific. Prices can vary quite a bit based on your car’s make, model, year, and whether the locksmith needs to deal with added tech (like key fobs or smart locks).
Average Cost of Rekeying a Car Lock in Detroit
- Basic key with manual lock: $50–$100 per lock
- Ignition rekeying: $100–$150
- Smart key systems: $150–$250+
Average Cost of Replacing a Car Lock in Detroit
- Door lock replacement: $100–$250 each
- Ignition replacement: $200–$400
- Remote key fob programming (if needed): $75–$150 extra
Quick Price Comparison Table
| Service | Cost Range in Detroit
|
|---|---|
| Rekeying door lock | $50–$100 per door |
| Rekeying ignition | $100–$150 |
| Replacing door lock | $100–$250 per lock |
| Replacing ignition lock | $200–$400 |
| Programming new key fob | $75–$150 |
Bottom line: In most cases, rekeying is the cheaper option, especially if your locks are still in good shape.
When Should You Rekey Your Car Locks?
Rekeying is a smart, affordable choice in several common scenarios:
1. You’ve Lost a Set of Keys
If you lost your car keys and you’re not sure where they ended up, rekeying your locks gives you peace of mind without paying for full replacement. It ensures the old key won’t work anymore.
2. Someone Might Have a Copy
Bought a used car? Gone through a breakup? If there’s a chance someone else has your key, rekeying is a quick fix that keeps you in control.
3. Lock Hardware is Still Functional
If your lock works fine mechanically and hasn’t been damaged in any way, there’s usually no need to replace the entire unit.
When Replacing Car Locks Makes More Sense
While rekeying can save you money, there are times when full replacement is the better option.
1. Locks Are Damaged or Worn Out
If your car door locks are sticking, difficult to turn, or visibly damaged, rekeying won’t solve the mechanical problem. Replacement is your best bet.
2. You’ve Been Locked Out Due to Theft or Vandalism
If someone stripped or tampered with your ignition or door lock during an attempted theft, it’s often necessary to replace damaged components.
3. You’re Upgrading Security
Older vehicles may have outdated lock systems that are easier to breach. Swapping in newer locks or electronic systems can be a worthwhile long-term investment.
What About Smart Keys and Electronic Lock Systems?
Many modern vehicles now use high-tech keyless entry systems and smart ignitions. These systems don’t use traditional locks in the same way, and that complicates the process.
With smart keys or key fobs:
- You’ll often need to replace or reprogram the fob.
- Rekeying may still be an option for backup manual locks.
- Costs for replacement and reprogramming are almost always higher.
If your car is less than 10 years old, check whether your locksmith has the tools to handle electronic systems. At Locksmiths of Detroit, we do.

FAQs About Rekeying vs. Replacing Car Locks in Detroit
How long does it take to rekey a car lock?
- Basic rekeying usually takes 30–60 minutes.
- Complex systems or multiple locks may take longer.
Can I just change the key without changing the lock?
Yes – that’s exactly what rekeying does. You’ll get a new key cut, and the internal pins in the lock will be adjusted to fit it.
Is it cheaper to rekey all locks or just one?
Rekeying multiple locks can often be bundled at a better rate. If cost is a concern, talk to your locksmith about options.
Do I need to rekey the ignition and door locks together?
Not necessarily, but it’s often more convenient to have one key that works on all locks.
Still Not Sure? Here’s How to Decide
If you’re weighing your options, here are some good rules of thumb:
- Go for rekeying if: The lock works well, you’ve just lost or misplaced keys, or you want a cost-effective way to secure your car.
- Choose replacement if: The lock is physically damaged, no longer works, or you’re upgrading your vehicle’s security.
