Car Key Replacement in St. Louis — All Key Types
Lost your car key or need a spare? Armour Locksmith provides complete car key replacement in St. Louis for all key types and vehicle generations:
- Traditional keys — standard metal key blanks cut to your vehicle’s specifications.
- Transponder keys — contain a microchip that communicates with your vehicle’s immobilizer. Must be programmed to your car’s ECU. We program on-site for most vehicles.
- Laser-cut (high-security) keys — precision cut with unique side-winding patterns for added security. Common on European and newer domestic vehicles.

Transponder Key Programming in St. Louis
Most vehicles manufactured after 1995 are equipped with transponder key immobilizer systems. When a key without the correct chip signal is used, the vehicle will not start — even if it is cut to the right shape. Armour Locksmith uses professional key programming equipment to pair new transponder keys to your vehicle’s immobilizer system.
We program transponder keys for all major manufacturers including:
- Ford, Lincoln, Mercury
- General Motors (Chevrolet, GMC, Buick, Cadillac)
- Chrysler, Dodge, Jeep, Ram
- Toyota, Lexus, Scion
- Honda, Acura
- Nissan, Infiniti
- BMW, Mini
- Mercedes-Benz, Sprinter
- Volkswagen, Audi, Porsche
- Hyundai, Kia, Genesis
- And most other makes sold in the United States
Key Fob Replacement and Programming in St. Louis
Key fobs control central locking, trunk release, panic alarms, and in many vehicles, remote start functionality. If your key fob is lost, damaged, or not responding, Armour Locksmith can supply and program a replacement fob for your specific vehicle — often at a fraction of dealership cost, with the added convenience of same-day, on-site service in St. Louis.
Ignition Repair and Replacement in St. Louis
A worn, damaged, or seized ignition cylinder can leave you stranded even if your key is in perfect condition. Signs your ignition needs service include:
- Key turns stiffly or gets stuck in the ignition
- Car won’t start even when the key is turned
- Key turns but ignition does not engage
- Ignition cylinder is visibly damaged or broken
Armour Locksmith diagnoses ignition issues on-site and provides repair or full cylinder replacement as needed. We work on both mechanical and electronic ignition systems throughout St. Louis.
Broken Car Key Extraction in St. Louis
A key that snaps off in a car door lock or ignition cylinder is a common and frustrating problem, especially with older metal keys. Attempting to remove a broken key with pliers or other improvised tools almost always makes the situation worse — pushing the fragment deeper into the lock. Armour Locksmith uses professional extraction tools to safely remove broken key pieces without damaging the lock or ignition cylinder.

Preventing Car Lockouts — Tips for St. Louis Drivers
While our team is always available for emergencies, the best lockout is one you avoid. Here are practical tips for St. Louis drivers:
- Keep a spare key — leave a spare with a trusted family member or neighbor, not hidden under your car (that’s the first place thieves check).
- Use a magnetic key box — if you must hide a spare, use a quality magnetic key box in a well-hidden location inside the wheel well.
- Check before you close — before closing your door, take a second to confirm your keys are in your pocket or purse, not on the seat.
- Enable unlock reminders — many modern vehicles have a key-in-ignition reminder chime. Check your vehicle settings to make sure it’s active.
- Add roadside assistance — many insurance carriers offer affordable roadside assistance add-ons that cover lockouts. Check your policy.
- Save our number — save Armour Locksmith’s number in your phone now so you’re not scrambling during a stressful lockout situation.
