Question 1

What is a transponder key?

Accepted Answer

A transponder key contains a small RFID chip inside the head that talks to the vehicle's immobilizer. When you turn the key, the immobilizer confirms the chip's ID before letting the engine start. Standard on almost every 1998-and-newer vehicle — a hardware-store copy without programming won't start the car.

Question 2

Can you make a transponder key without the original?

Accepted Answer

Yes. We originate transponder keys through the immobilizer when all originals are lost. Cut the blade by code from VIN, program the chip, done — no tow required.

Question 3

How much does a transponder key cost in Denver?

Accepted Answer

Service call starts at $49. Transponder keys are one of the more affordable key types; final pricing depends on the make and whether we're duplicating an existing key or originating one.

Question 4

Why won't my new key start the car?

Accepted Answer

Because it's not programmed. Cutting a matching blade at a hardware store gets you a key that turns the lock but doesn't satisfy the immobilizer. We program the chip to your vehicle so the engine actually starts.

Question 5

Can you duplicate a transponder key from an existing one?

Accepted Answer

Yes — transponder duplication is one of our most common jobs. Cheaper and faster than originating a key with no original present.

Question 6

Can you program OEM transponder keys?

Accepted Answer

Yes. Bring your OEM key or we can source one; we cut and program on-site.

Question 7

Can you program aftermarket transponder keys?

Accepted Answer

Yes, in many cases. OEM-quality aftermarket transponder keys work reliably on many vehicles at meaningfully lower cost.

Question 8

How long does transponder programming take?

Accepted Answer

Duplicate: 20–45 minutes on-site. All-keys-lost origination: 45–90 minutes on most vehicles.

Question 9

Do transponder keys wear out?

Accepted Answer

The chip itself is very durable, but the plastic head can crack from being dropped or sat on. If the chip is intact we can transplant it into a new housing; if not, we program a fresh key.
