Extra Keys: Smart Ways to Keep Spare Keys SecureHaving extra keys is a small convenience that can save you time, money, and stress. But if spare keys fall into the wrong hands, they become a serious security risk. This article covers practical, modern, and sensible ways to keep spare keys secure — from traditional methods and clever hiding spots to smart alternatives and emergency planning.
Why securing spare keys matters
A spare key is only useful if it’s available when needed and inaccessible to burglars or opportunistic strangers. Unauthorized access via a spare key can lead to theft, identity exposure, and long-term security problems (like needing to replace locks). Balancing accessibility for trusted people with protection from others is the core goal.
Assessing risk: who needs access?
Before choosing where and how to store spare keys, consider who legitimately needs them:
- Family members and roommates
- House sitters, cleaners, or maintenance workers
- Trusted neighbors or nearby friends
- Pet sitters and childcare providers
Limit the number of spare copies to the minimum necessary. Each additional copy increases the risk of loss or misuse.
Traditional secure methods
- Key safes: Wall- or door-mounted lockboxes that open with a combination or code. Secure and convenient for providing temporary access to cleaners, contractors, or guests. Choose a model rated for outdoor use, with tamper-resistant features and an adjustable code. Mount in a hidden but accessible location and change the code after each non-regular use.
- Home safe: For long-term storage of keys along with important documents, a heavy, anchored safe provides strong protection. Make sure it’s fire- and water-resistant if you’re storing irreplaceable items with the keys.
- Trusted person: Giving a spare to someone you absolutely trust (a close relative or very reliable neighbor) removes the need for hiding. Keep an inventory of who has copies.
Hiding spots — what works and what to avoid
Good hiding spots reduce the chance a burglar finds your key quickly. Avoid obvious choices like under the doormat, inside a flowerpot by the door, or under a fake rock right at the entry — burglars always check those first.
Better hiding ideas:
- Inside a lockbox or key safe (as above) mounted out of line-of-sight.
- Inside a secured garage, shed, or internal storage area that requires another key or code to access.
- With a trusted neighbor who lives nearby and is often home.
- In a less-obvious outdoor feature well away from the front door: for example, fastened underneath a rarely used outdoor furniture piece or inside a vent with a locked cover (ensure it’s weatherproof).
Spots to avoid:
- Hiding places commonly recommended online (under plants, mailboxes, stones) — burglars know these too.
- On the keyring with identifying tags (address labels make it easy for thieves).
- Locations that can be accessed without entering the property (like fences or gates that can be opened).
Use technology: smart locks and electronic access
Smart locks and electronic access systems reduce the need for physical spare keys:
- Keypad locks: Create temporary or permanent numeric codes for different people. Codes can be changed anytime and often tracked.
- Bluetooth/Wi‑Fi smart locks: Grant access via phone apps; some allow guest codes or time-limited access. Ensure your home network is secure and use strong, unique passwords for accounts.
- Smart lock best practices: Use two-factor authentication where available, keep firmware up to date, and set unique temporary codes for occasional users.
These systems shift the risk from physical key theft to digital security; protect accounts and your home network accordingly.
Key duplication: keep it controlled
If you must make copies:
- Use a reputable locksmith or hardware store. Consider key blanks marked “Do not duplicate” for important locks, though they are not foolproof.
- Keep a record of who has copies and when they were made.
- Reclaim or destroy old copies when someone no longer needs access.
For high-security needs, consider rekeying locks when losing track of copies.
Emergency access planning
Plan for situations where you can’t reach your spare key:
- Use a key safe with a code you can share remotely.
- Designate multiple trusted people with staggered access (e.g., a neighbor and a family member).
- Keep a digital copy of important lock or key information (serial numbers, locksmith contact) in a secure password manager or encrypted note—do not store photos of keys in cloud services without strong encryption.
Protecting keys from duplication and tampering
- High-security locks: Invest in locks that use restricted keys requiring proof of ownership to duplicate. These keys have patented profiles and are harder to copy.
- Tamper evidence: Use small tamper-evident tags on key rings so you notice if a set has been opened or accessed.
- Periodic audits: Regularly check who has keys and whether any copies are unaccounted for.
When to replace or rekey
Replace or rekey locks if:
- You lose track of a spare key and can’t confirm who has it.
- Tenants move out, or a relationship changes (divorce, breakup).
- You suspect unauthorized duplication or tampering.
- You want to upgrade to higher security (smart locks or restricted-key systems).
Rekeying is often cheaper than replacing the entire lock but still restores control quickly.
Cost vs. convenience: choosing the right approach
- Low cost, moderate security: Give a spare to a trusted neighbor or hide it cleverly (but avoid obvious spots).
- Moderate cost, higher security: Purchase a keyed lockbox or keypad lock.
- Higher cost, best convenience: Smart locks with temporary codes and logging features.
Consider how often you’ll need the spare, who will use it, and how much risk you can accept.
Quick checklist for secure spare key management
- Limit the number of copies.
- Use a lockbox, safe, or trusted person.
- Avoid common hiding spots.
- Prefer temporary codes or smart access when possible.
- Track who has keys and change codes after use.
- Rekey or replace locks when control is lost.
Securing spare keys is a mix of practical habits, sensible hardware choices, and planning. The right combination depends on your household, budget, and preferred balance of convenience and security.
