Tech Tips from AutoJet Locksmith

Losing your car keys is a nightmare, but solutions are faster and more accessible than ever. Whether you're dealing with traditional metal keys, transponder chips, or smart fobs, here's a step-by-step guide to getting back on the road without breaking the bank.

Step 1: Stay Calm and Assess the Situation

First, double-check common spots: pockets, bags, under seats, or the trunk. If you're sure they're gone, note your vehicle's make, model, year, and VIN (Vehicle Identification Number). This info is crucial for replacement.

Step 2: Check for Spares or Alternatives

Many modern cars have app-based unlocks via manufacturers like Tesla or Ford. If you have a spare at home or with a trusted friend, use that. For older models, a metal key might open doors even if it doesn't start the engine.

Step 3: Call a Professional Automotive Locksmith

Skip the dealership—mobile locksmiths like AutoJet can come to you, cut new keys, and program them on-site using OBD-II tools. Expect costs from $150-$500, far less than dealer fees. We're available 24/7 in Olympia, WA.

Step 4: Prevent Future Losses

Invest in key trackers like Tile or AirTag. Always have at least one spare programmed. For high-tech keys, consider insurance riders that cover replacements.

Pro Tip: If your car uses push-to-start, battery issues in the fob can mimic lost keys—try replacing it first.

Push-to-start systems, also known as smart key or keyless entry, are standard in most new vehicles. Here's a crisp breakdown of how they operate and tips for maintenance.

How It Works

The fob communicates with the car's computer via radio frequencies (RFID). When you're within range (usually 3-5 feet), the doors unlock automatically. Press the brake and push the button to start—no key insertion needed.

Key Components

- Fob Battery: CR2032 type, lasts 2-3 years. Low battery causes intermittent issues.
- Immobilizer: Prevents theft by verifying the fob's chip.
- Antenna: In the car, detects the fob's signal.

Common Issues & Solutions

Dead battery? Hold the fob against the start button. Lost fob? Call us for on-site programming—dealers can take days. Cost: $200-400 for replacement.

Security Tips

Use signal-blocking pouches to prevent relay attacks. Always have a spare programmed to avoid lockouts.

Pro Tip: For EVs like Tesla, app access can bypass fobs, but physical keys are still essential for reliability.

The ignition cylinder is the mechanical heart of your car's start system. Spot these signs early to avoid breakdowns.

Laser-cut keys (sidewinder) vs traditional: Security meets convenience.

Traditional Keys

Edge-cut with jagged teeth. Easy to duplicate at hardware stores ($5-10). Vulnerable to bumping/picking.

Laser-Cut Keys

Milled on both sides with grooves. Require specialized machines for duplication ($50-150). High-security: Resist picking, harder to bump.

Common Vehicles

Laser-cut: BMW, Mercedes, Audi, newer Toyotas. Traditional: Older models, basic trims.

Pros & Cons

Laser: Secure, durable; Cons: Costly to replace.
Traditional: Cheap, easy; Cons: Less secure.

Replacement Tips

We cut laser keys on-site with precision tools. Avoid cheap duplicates—they wear faster.

Pro Tip: Upgrade to laser-cut for better theft protection.
