Immobilizer reflash done on an older Toyota/Lexus, allowing us to successfully program brand-new keys after all existing keys were lost.

Fortunately, we have the specialized equipment and expertise to perform these procedures and get your vehicle running again—without replacing expensive modules.

⚠️ Before You Hire Someone for a Vehicle Lockout... Read This! 🚗🔑

We've recently seen an increase in people advertising automotive lockout services on Facebook Marketplace with little or no professional training. While the low price may seem appealing, improper tools and techniques can lead to expensive damage such as:

❌ Scratched paint and damaged window trim
❌ Bent door frames causing wind noise or water leaks
❌ Broken weatherstripping and clips
❌ Damaged lock mechanisms and door handles
❌ Costly repairs that far exceed the original service call

A vehicle lockout should be completed with the proper tools, training, and experience to avoid unnecessary damage.

At CSE Lock & Key LLC, we are a licensed and insured professional locksmith business. We use industry-approved methods to gain entry safely while treating every vehicle with care and respect.

When choosing a locksmith, don't just ask for the price—ask if they're a licensed business, insured, and experienced with automotive locksmith work. Protect your vehicle and your wallet by choosing a professional.
