Not every lock problem requires a call to the locksmith. If you’re a DIY enthusiast or landlord in Albuquerque, there are some lock maintenance and upgrade tasks you can handle on your own. By learning a few locksmith tips, you can improve your home’s security and save money. This post will cover how to rekey locks yourself, perform routine lock maintenance, and recognize when a job is better left to a professional.

Understanding Rekeying vs. Replacing Locks
One of the most common DIY locksmith tasks is rekeying a lock. Rekeying means changing the internal pins of a lock so that it no longer works with the old keys – you’ll use a new key instead. This is a cost-effective way to “reset” your locks if you’re concerned about lost or unreturned keys. (Landlords often rekey between tenants for this reason.)
To rekey a lock yourself, you’ll need a rekey kit specific to your lock brand. These kits are available at hardware stores and come with tiny pins, tools, and instructions. Basic steps to rekey a standard pin-and-tumbler lock include removing the lock from the door, disassembling the cylinder, replacing the old pins with new ones from the kit (matched to a new key), and reassembling the lock. After rekeying, always test the new key to ensure it turns smoothly.
It’s a delicate process, but very doable with patience. Make sure to work over a tray or towel so you don’t lose tiny pins. If you feel uncomfortable or the lock is complex (electronic locks, high-security locks), it’s okay to stop and call a locksmith. Don’t force anything – you don’t want to damage the lock mechanism.
Routine Lock Maintenance Tips
Even quality locks need a little attention over the years. Here are some DIY maintenance tips to keep them working smoothly:
Lubricate Locks Annually: Over time, dirt and grime can make a lock sticky or hard to turn. Use a graphite or silicone-based lubricant (avoid oil-based products that gum up). A quick spray into the keyway and on the bolt can make keys glide again.
Tighten Loose Hardware: Check your door’s strike plates, hinges, and handle screws. Tighten any that are loose. A misaligned strike (the metal plate on the door frame) can cause the deadbolt to not set fully, compromising security.
Upgrade to Longer Screws: A pro tip is to replace the short screws (often 1/2-inch) in your strike plate and hinges with 3-inch screws. Longer screws anchor into the wall stud, vastly strengthening the door against forced entry.
Test Deadbolts: A deadbolt should fully extend into the door frame. If it doesn’t or is hard to turn, the alignment might be off. You may need to adjust the strike plate or slightly enlarge the hole behind the strike so the bolt extends completely.
By staying on top of these small tasks, you’ll extend the life of your locks and maintain security.
Enhance Security with Simple DIY Locksmith Tips
Beyond maintenance, there are a few DIY Locksmith Tips that significantly improve your home’s security:
Reinforce Doors and Windows: As primary entry points, these deserve attention. Did you know 34% of burglars enter through the front doorcovesmart.com (often because it’s left unlocked or uses a weak lock)? Install a quality deadbolt if you don’t have one. Consider adding a door reinforcement plate or door bar for extra protection against kick-ins. Secure sliding doors with a bar or dowel in the track to prevent forcing them open.
Smart Locks or Keypads: Upgrading one or two entry points to a smart lock can be a DIY project (many models are designed for easy installation). Smart locks eliminate physical keys – you use a code or smartphone app. They add convenience and solve the problem of keys under the doormat. Many retrofit over existing deadbolts without much fuss.
Security Systems: While not exactly a “lock” tip, installing a DIY security system (like a smart doorbell camera or motion sensor alarm) can complement your locks. These systems can alert you and deter burglars if someone tries to tamper with your doors.
Know Your Limits – When to Call a Locksmith
While DIY lock work can handle basic tasks, recognize when to call in a professional. Situations where you should call a locksmith include dealing with high-security or commercial-grade locks (which need specialized tools), electronic or alarm-connected locks (to avoid voiding warranties), repairing damage after a break-in, or when a DIY fix doesn’t solve the issue. There’s no shame in getting expert help to secure your home properly.
Professional locksmiths also provide valuable peace of mind. They can inspect your DIY work and tweak anything that might be off, ensuring everything is perfectly in order. For complex projects like installing whole-home master key systems or repairing a severely damaged lock, you’ll save time and potential frustration by using a pro from the start.
For homeowners in Albuquerque, having a relationship with a trusted local locksmith is invaluable. You can handle the basic upkeep, but when you need help, call Just In Time Locksmith, Albuquerque NM, (505) 818-0720. They can rekey, repair, or upgrade your locks to the latest standards.
