What to Have Ready When You Call
- Year, make, and model of the vehicle (e.g., 2019 Toyota RAV4 Limited).
- VIN — printed on the driver-side dashboard at the base of the windshield, on the door jamb sticker, or on your insurance card.
- Photo ID matching the vehicle registration or title (Texas DPS rules require ownership verification before we cut a key).
- How many working keys you currently have — "all keys lost" jobs require additional onboard programming time.
- Your exact location with cross street or business name so dispatch can route the closest van.
If your only key is locked inside a running vehicle and a child or pet is inside, call 911 first, then call us — we treat these as priority dispatch.

Real DFW Job Example
A common Frisco call: a 2020 Toyota RAV4 owner lost both keys at Stonebriar Mall on a Saturday afternoon. We dispatched a van from our Plano coverage zone, arrived in 28 minutes, generated a new key from the door lock and VIN, and programmed the smart fob to the vehicle's immobilizer in another 41 minutes. Total time on-site: under 75 minutes. Total cost was inside our published proximity-key range — no tow, no dealership appointment, no overnight wait.
Car Key Types We Replace
Modern vehicles use increasingly sophisticated key technology. MyKey Locksmith replaces and programs every type of automotive key on the market today. Understanding the differences between key types helps you know what to expect when you call for service.
Transponder Keys
Transponder keys contain a small electronic chip embedded in the key head that communicates with your vehicle's immobilizer system. When you insert the key, the car's computer sends a signal to the chip — if the code matches, the engine starts. If it doesn't match, the vehicle won't start even if the key's physical cut is correct. MyKey Locksmith programs transponder chips for all makes and models, ensuring the electronic handshake between key and car works perfectly. Most vehicles manufactured after 2000 use transponder technology.
Smart Keys & Proximity Remotes
Smart keys, also called proximity keys or intelligent keys, allow you to unlock and start your vehicle without physically inserting a key. The car detects the smart key in your pocket or bag and enables push-button start. These keys use rolling-code encryption for security. We program smart keys and proximity remotes for Toyota, Honda, Nissan, Ford, Chevrolet, Hyundai, Kia, BMW, Mercedes, Lexus, Audi, and all other major brands. Our mobile units carry the advanced programming equipment required for the latest smart key systems.
Key Fobs & Remotes
Key fobs control your vehicle's remote lock, unlock, trunk release, and panic alarm functions. Some vehicles use a separate key fob alongside a traditional key, while others integrate everything into a single unit. We program standalone key fobs, integrated key-fob combinations, and aftermarket remotes. If your key fob stops working, we diagnose whether the issue is a dead battery, signal interference, or a programming problem — and fix it on the spot.
Flip Keys & Switchblade Keys
Flip keys feature a foldable metal blade that retracts into the key body when not in use. Popular on Volkswagen, Audi, Kia, Hyundai, and other brands, flip keys combine a transponder chip and remote buttons in a compact design. We cut and program flip keys and replace cracked or worn flip key shells while transferring your existing electronics.
Vehicle Brands We Service
MyKey Locksmith replaces keys for virtually every vehicle on the road. Our most commonly serviced brands include Ford, Chevrolet, Toyota, Honda, Nissan, Hyundai, Kia, BMW, Mercedes-Benz, Audi, Lexus, Volkswagen, Dodge, Jeep, Subaru, Mazda, GMC, Cadillac, Infiniti, Acura, Land Rover, Jaguar, Porsche, and Volvo. Whether you drive a domestic truck, an imported sedan, or a European luxury vehicle, our mobile automotive locksmith has the equipment and expertise to create your new key on-site.
Our Car Key Replacement Process
When you call MyKey Locksmith for a car key replacement, here's exactly what happens. First, our dispatcher confirms your vehicle's year, make, model, and VIN to ensure our technician arrives with the correct key blank and programming tools. Second, our mobile locksmith drives to your location — whether that's your home, workplace, parking lot, or roadside. Third, we verify vehicle ownership through your registration or ID. Fourth, we cut your new key using precision key-cutting equipment mounted in our service van. Fifth, we program the transponder chip or smart key to your vehicle's immobilizer using professional-grade diagnostic tools. Finally, we test the key thoroughly — checking start, lock, unlock, and remote functions — before completing the job. The entire process typically takes 30-60 minutes depending on your vehicle type.
Car Key Replacement vs. Dealership
Many vehicle owners assume they must go to the dealership for a replacement key. In reality, a licensed automotive locksmith like MyKey provides the same key quality at significantly lower cost with far greater convenience. Dealerships typically charge $200-600 for a replacement key and require you to tow your vehicle to their location or wait days for a key to be ordered. MyKey Locksmith comes to you, completes the job on-site in under an hour, and charges competitive prices with no towing fees or waiting periods. We use the same professional-grade key blanks and programming protocols as dealerships.
Frequently Asked Questions
How much does car key replacement cost in Dallas?
Car key replacement costs depend on your vehicle type and key technology. Basic transponder keys typically cost $150-250 including cutting and programming. Smart keys and proximity remotes range from $200-400. Luxury vehicle keys (BMW, Mercedes, Audi) may cost $300-500. We provide an exact quote over the phone based on your vehicle's year, make, and model before dispatching a technician.
Can you make a car key if I lost all my keys?
Yes, we can create a new key from scratch even if you have zero working keys. Our technician reads your vehicle's lock or uses diagnostic tools to determine the correct key cut, then programs the new key's transponder chip to your car's immobilizer system. This "all keys lost" service is available for most vehicle makes and models.
How long does car key replacement take?
Most car key replacements take 30-60 minutes from arrival. Simple transponder keys are typically completed in 20-30 minutes. Smart keys and proximity remotes may take 45-60 minutes due to more complex programming procedures. Luxury and newer vehicles with advanced encryption may require additional time.
Do you come to my location?
Absolutely. MyKey Locksmith is a fully mobile automotive locksmith service. We come to your home, office, parking lot, or roadside location anywhere in the Dallas-Fort Worth metroplex. Our service vans are fully equipped mobile workshops with everything needed to cut and program your new key on-site.
Can you program a key I bought online?
In many cases, yes. However, we recommend caution with aftermarket keys purchased online — some may not be compatible with your vehicle's immobilizer system or may fail prematurely. We can program customer-supplied keys when they meet the correct specifications, but we cannot guarantee keys we didn't supply. For reliable results, we recommend using our professional-grade OEM-compatible key blanks.
