Key Control: Why You Should Never Label Your Keys

One lost keychain can compromise your entire security system. Learn the professional approach to key management, from color-coding strategies to emergency backup plans.

You've lost your keys. On the keychain is a tag with your name and address—you know, so someone can return them if found. Seems responsible, right?

Wrong. You've just handed a stranger everything they need to access your home, car, and possibly your workplace. This is just one of many key control mistakes we see daily as Maryland locksmiths.

The Labeling Problem

Why People Label Keys:

"If someone honest finds them, they can return them!"

The Reality:

  • Most found keys are never returned (even by honest people)
  • Labels identify which key is which for potential thieves
  • Combined with address, you've created a security disaster
  • You've told thieves you're not home (because you lost your keys somewhere else)
  • Real Scenario:

    Keys found in a parking lot with address tag. Before the owner even realizes they're missing, their home has been burglarized. The thief knew:

  • Where you live
  • That you weren't home
  • Which key opened which lock
  • That you probably haven't changed locks yet
  • The Right Way to Identify Keys

    If you need to distinguish between keys, here are secure methods:

    Color-Coding System:

  • Use different colored key caps
  • Only you know what each color means
  • Doesn't reveal any information if lost
  • Example:

  • Blue = front door
  • Red = back door
  • Green = garage
  • Yellow = office
  • Number or Symbol System:

  • Engrave a simple number or symbol
  • Keep a private legend at home
  • No identifying information on the keychain itself
  • Physical Differences:

  • Use keys that look distinctly different
  • Modern keys come in various shapes and colors
  • Easy to distinguish visually without labels
  • What Should NEVER Be on Your Keychain

    Absolutely Never Include:

    1. Your name

    2. Your address

    3. Phone number

    4. "Home" labels

    5. "Office" labels

    6. License plate numbers

    7. Any identifying information

    Also Avoid:

  • Gym membership cards with address
  • Store loyalty cards with your info
  • Work ID badges
  • Anything that identifies you or your location
  • Why This Matters:

    If someone with bad intentions finds your keys, the less information they have, the better. A set of anonymous keys is useless without knowing what they unlock.

    The Keychain Bulk Problem

    We see keychains with 20+ keys, most of which the owner doesn't even remember what they open.

    Why This Is a Security Risk:

  • Makes key loss more impactful
  • Harder to notice when one is missing
  • Difficult to track what you actually have
  • Worn or broken keys can damage locks
  • Heavy keychain damages car ignition
  • The Better Approach:

    Carry only what you need daily:

  • House keys (front and back door)
  • Car key
  • Work keys if needed
  • Maybe one or two others
  • Store rarely-used keys separately:

  • Storage unit keys
  • Seasonal property keys
  • Old locks you're "keeping just in case"
  • Creating a Key Management System

    Professional key control isn't complicated, but it requires intentionality:

    Step 1: Audit Your Keys

    Right now, do you know:

  • Exactly how many keys you have?
  • What each one opens?
  • When you last used each one?
  • Who has copies?
  • If you answered "no" to any of these, you have a key control problem.

    Step 2: Consolidate and Eliminate

  • Get rid of keys to locks you no longer own
  • Combine key systems where possible (rekey multiple locks to one key)
  • Securely dispose of old keys (don't just throw in trash)
  • Step 3: Create Separate Keysets

  • Daily carry: Only essential keys
  • Home storage: Less frequently needed keys
  • Safe/secure location: Emergency and backup keys
  • Step 4: Track and Document

    Keep a private record at home:

  • What each key opens
  • When you had copies made
  • Who has copies
  • When locks were last rekeyed
  • The Backup Key Strategy

    Everyone should have a backup plan for when keys are lost:

    Good Backup Options:

    1. Hide-A-Key in Non-Obvious Location

  • Never under doormat, flowerpot, or above door frame
  • Consider magnetic boxes in less obvious spots
  • Change location periodically
  • 2. Trusted Neighbor

  • Someone who's usually home
  • Has good security themselves
  • You trust implicitly
  • 3. Secure Lockbox with Combination

  • Mounted somewhere discrete
  • Combination access (not keyed)
  • Check periodically to ensure it's still there
  • 4. Smart Locks

  • Keypad entry as backup
  • Temporary codes for emergencies
  • Phone-based access
  • Bad Backup Options:

  • Under any obvious hiding spot
  • With ex-partners or former friends
  • Office desk drawer (if keys are for home)
  • Inside your car (which is also locked)
  • When to Rekey vs. Change Locks

    Rekey Immediately If:

  • You've lost keys with identifying information
  • You ended a relationship with someone who had keys
  • You fired an employee who had keys
  • You moved into a new home
  • You found unknown keys that might be yours
  • Rekeying Costs:

  • $20-40 per lock
  • Takes 15-30 minutes
  • Your existing locks work with new keys
  • Old keys no longer work
  • This is much cheaper than replacing locks entirely and just as effective.

    Key Duplication Best Practices

    When Getting Keys Copied:

    Do:

  • Use reputable locksmiths
  • Show ID if requested
  • Get quality copies (cheap cuts wear fast)
  • Test copies before leaving the store
  • Don't:

  • Use random mall kiosks
  • Copy keys for people you're unsure about
  • Make "extra" copies "just in case" (they usually end up lost)
  • High-Security Keys:

    Consider restricted keyway locks that:

  • Cannot be copied at hardware stores
  • Require authorization from locksmith
  • Provide proof of copy control
  • Cost more initially but offer better security
  • Brands with restricted keyways:

  • Medeco
  • Mul-T-Lock
  • Abloy
  • Primus
  • Digital Key Management

    Modern technology offers alternatives to physical keys:

    Smart Lock Advantages:

  • No physical keys to lose
  • Generate temporary codes for guests
  • Revoke access instantly
  • Activity logs show who entered when
  • Smart Lock Considerations:

  • Battery backup plan needed
  • Still have physical backup key
  • Security of digital system
  • Cost ($200-400 per lock)
  • What to Do When You Lose Keys

    Act immediately:

    Step 1: Assess the Risk

    High risk (act within 24 hours):

  • Keys had identifying information
  • Lost in area near your home/work
  • Set included multiple important keys
  • Medium risk (act within a week):

  • Anonymous keys
  • Lost far from home
  • Only a few keys affected
  • Step 2: Immediate Actions

    1. Check with locations you visited (lost and found)

    2. Alert household members to increased vigilance

    3. Consider temporary security (change alarm codes, add extra locks)

    Step 3: Long-term Solution

  • Rekey affected locks (most cost-effective)
  • Upgrade to high-security locks (if rekeying anyway)
  • Implement better key control going forward
  • Commercial Key Control

    Business owners have additional key management challenges:

    Employee Key Issues:

  • Who has keys?
  • When were copies made?
  • Are keys collected when employees leave?
  • Master Key Systems:

  • Offer convenience but create vulnerability
  • Require professional management
  • Should be audited regularly
  • Professional Commercial Key Control:

  • Electronic access control systems
  • Audit trails of entry/exit
  • Easy revocation of access
  • No physical keys to lose
  • Children and Key Responsibility

    Teaching kids key management:

    Appropriate Ages:

  • 10-12 years: May be ready for supervised key use
  • 13-15 years: Can likely manage with oversight
  • 16+: Should demonstrate responsibility
  • Teaching Key Safety:

  • Never label keys
  • Keep attached to backpack or person
  • Don't show keys to friends
  • Report loss immediately
  • Don't make copies for friends
  • If They Lose Keys:

  • Natural consequence: rekey cost comes from allowance
  • Teaching moment about responsibility
  • System review to prevent future loss
