Your home is your sanctuary. When something goes wrong with your locks — whether you're locked out at midnight or moving into a new house — Princeton Pro Locksmith is there fast, with the tools and expertise to handle it right.

  • Emergency Lockout

    Locked out of your home? We arrive in 30 minutes or less, 24 hours a day, 7 days a week — no extra charge for nights or weekends.

  • Lock Rekeying

    Moving into a new home? Just had a breakup or lost your keys? Rekeying changes the internal pins so old keys no longer work — faster and cheaper than full replacement.

  • Lock Installation & Upgrade

    We install deadbolts, smart locks, and high-security locks from trusted brands like Schlage, Kwikset, and Medeco.

  • Broken Key Extraction

    Key snapped in the lock? We extract it cleanly without damaging the lock cylinder, then cut you a new key on the spot.

  • Security Consultation

    Not sure how secure your home is? We'll walk through your entry points and recommend upgrades that fit your budget.
