How Long Does It Take to Rekey a Lock – Can I Rekey a Lock Myself?

December 3, 2024

Rekeying a lock is an essential service that ensures your security, whether you’ve moved into a new home, lost your keys, or want to prevent access from someone who previously had a key. If you’re wondering how long this process takes or if it’s something you can do yourself, you’re in the right place. This guide covers every aspect of lock rekeying, from the time it takes to the steps involved and DIY considerations.


5 Reasons Why Rekeying is Better Than Replacing Your Locks


What Does It Mean to Rekey a Lock?

Rekeying a lock involves changing the internal pins and tumblers so that an old key no longer works. Instead, a new key is created to match the modified lock mechanism. Unlike replacing the entire lock, rekeying is a cost-effective way to enhance security without significant hardware changes.


Why Would You Need to Rekey a Lock?


1. Moving to a New Home

When moving, rekeying ensures previous residents or anyone with an old key can no longer access your home.

2. Lost or Stolen Keys

Losing keys or having them stolen poses a security risk. Rekeying ensures unauthorized individuals cannot use the old keys.

3. Upgrading Security

Rekeying allows you to standardize locks, enabling one key to open multiple doors, simplifying access without compromising security.


How Long Does It Take to Rekey a Lock?


1. Professional Rekeying Time

A professional locksmith typically takes 15-30 minutes to rekey a single lock. The exact time depends on the lock type and the locksmith’s experience.

2. Rekeying Multiple Locks

Rekeying multiple locks to the same key can take 30 minutes to an hour, depending on the number of locks and their complexity.

3. DIY Rekeying Time

If you choose the DIY route, expect to spend 30 minutes to an hour per lock, especially if it’s your first time. Gathering tools, reading instructions, and troubleshooting may extend the process.


Can You Rekey a Lock Yourself?


The DIY Option

Yes, you can rekey a lock yourself with a rekeying kit that matches your lock’s brand and model. These kits include tools, instructions, and replacement pins to help you modify the lock.


Tools You’ll Need

  • A rekeying kit
  • A screwdriver
  • Replacement pins (included in most kits)
  • Tweezers or pliers (for precision)


Step-by-Step Guide to Rekeying a Lock Yourself


1. Purchase the Right Rekeying Kit

Buy a kit that is compatible with your lock brand. Popular kits are available for brands like Kwikset and Schlage.

2. Remove the Lock from the Door

Using a screwdriver, carefully remove the lock and set the screws aside.

3. Disassemble the Lock Cylinder

Access the cylinder by following the instructions in your rekeying kit.

4. Replace the Old Pins with New Ones

Insert the new pins into the lock cylinder according to the provided key pin chart.

5. Test the New Key

Before reassembling, test the new key to ensure smooth operation.

6. Reassemble the Lock

Reattach the lock to the door, ensuring all components are secure.


Challenges of DIY Rekeying


1. Compatibility Issues

Not all locks are DIY-friendly. Some high-security locks require specialized tools.

2. Precision Needed

Pins and tumblers are small and require steady hands and precision tools.

3. Risk of Damage

Improper handling can damage the lock, requiring professional replacement.


When to Call a Professional Locksmith


1. Complex Lock Systems

For advanced or high-security locks, professional expertise ensures the job is done correctly.

2. Lack of Tools

If you don’t have the necessary tools or experience, hiring a locksmith saves time and potential frustration.

3. Time-Sensitive Situations

When you need immediate results, a locksmith provides quick and reliable service.


Cost Comparison: DIY vs. Professional Rekeying


DIY Rekeying Costs

  • Rekeying kit: $15–$30
  • Time investment: Significant

Professional Rekeying Costs

  • Per lock: $20–$50
  • Convenience: High


Benefits of Rekeying Over Replacing


1. Cost-Effectiveness

Rekeying is significantly cheaper than replacing an entire lock.

2. Environmentally Friendly

Rekeying reduces waste by reusing the existing lock hardware.

3. Customization

Rekeying allows you to match multiple locks to a single key.


How Often Should You Rekey Your Locks?


  • After Moving In: Always rekey when moving into a new property.
  • Every Few Years: Routine rekeying maintains security, especially in rental properties or shared spaces.
  • After a Security Breach: Rekey immediately if you suspect unauthorized access.


FAQs About Rekeying Locks

Can I Rekey a Smart Lock Myself?

Some smart locks have rekeying capabilities, but many require professional assistance.

Both options enhance security, but rekeying is more cost-effective if the hardware is intact.


Final Thoughts: DIY Rekeying vs. Hiring a Professional

Rekeying a lock is a valuable skill that can save you money and enhance security. While it’s possible to do it yourself with the right tools and patience, hiring a professional ensures accuracy, especially for complex locks. Assess your comfort level, tools, and time before deciding the best approach for your needs.
