Car Key Programming FAQs

Common questions about our Car Key Programming services

Car key programming costs vary depending on your vehicle’s make, model, and key type. Basic transponder keys typically range from $150-$250, while more advanced smart keys can cost $250-$400. We provide exact pricing based on your specific vehicle requirements. Our prices are significantly lower than dealership rates, and we use the same quality OEM parts and professional programming equipment. There are no hidden fees – the price we quote includes programming, testing, and ensuring your existing keys continue to work properly.
Yes, we can program new keys even when you’ve lost all your original keys. This process, called “key origination,” requires specialized equipment to access your vehicle’s computer system and create new master keys. While this is more complex than programming additional keys when you have a working original, our technicians have the professional tools and expertise to handle these situations. The process typically takes longer than standard programming, but we can usually complete the work the same day and get you back on the road.
Most car key programming jobs are completed in under 30 minutes. The exact time depends on your vehicle’s make, model, and the type of key being programmed. Simple transponder keys are typically faster, while advanced smart keys or situations where all keys were lost may take longer. We work efficiently to minimize your downtime, and most customers can wait while we complete the programming. For complex jobs, we’ll provide a realistic time estimate upfront so you can plan accordingly.
When done properly with professional equipment, programming a new key should not affect your existing keys. Our technicians use manufacturer-approved programming procedures that add new keys to your vehicle’s system without erasing existing ones. However, this is why professional programming is so important – DIY attempts or inexperienced technicians can accidentally erase all programmed keys, leaving you completely locked out. We test all existing keys after programming to ensure everything works correctly before completing the job.
