GMC Sierra Key Replacement Options by Era
GMC Sierra keys have changed over the years. The model year and the key system your truck uses help determine whether you need a traditional key, a chip key, a flip key or a smart key.
Through about 2006: mostly metal keys
Older Sierra trucks mostly used metal keys. If yours has a conventional key, tell us the year and describe whether the key is lost, worn or damaged when you call.
From about 2007: chip keys
Chip keys became common in GMC trucks from about 2007. A replacement may involve both a cut key and the vehicle’s electronic key system, so a plain-looking key may not be the whole solution.
Later model years: flip and smart keys
Later Sierra model years may use flip or smart keys. These keys can differ in how they operate, so share the model year and the kind of key or fob you have, if you know.

How Sierra Trims and Cab Styles Affect Key Replacement
Sierra trucks come in different cab and trim configurations, and the key setup is not identified by the name on the trim badge alone. The model year and the key system are important details when arranging a replacement.
Cab and body configuration
When you call about a GMC Sierra key, mention the truck’s year and cab or body style. Those details help describe which Sierra you drive without assuming every configuration uses the same key.
Trim and installed key system
A trim name by itself does not tell you whether the truck uses a metal key, chip key, flip key or smart key. If you have a working key or fob, describe its shape and how you use it.
Key versus fob needs
Some drivers need a replacement key, while others need a fob replaced or its functions programmed. Tell us what stopped working so we can discuss the right type of service for your Sierra.

GMC Sierra Key and Key Fob Services We Provide
We provide mobile locksmith service and help with common key problems for GMC Sierra owners. Ask about GMC key replacement if you drive another GMC model.
- Lost all your keys — We make a new car key on site when all keys are lost. Share the Sierra’s year and the key type, if known, when you call.
- GMC Sierra key fob replacement — If your fob is missing or damaged, tell us what it looks like and what functions you need from the replacement.
- GMC Sierra key fob programming — We offer key fob programming for customers who need help with a fob’s electronic functions.
- A key that is worn or damaged — We can help with car key repair when a key is no longer working as it should. Describe the problem before service so we understand what the key is doing.
- Locked out of your Sierra — If the keys are inside the truck, ask for car lockout help rather than a replacement key.
Bought a Used GMC Sierra With One Key?
If your used Sierra came with just one key, arranging a spare before that key fails gives you another option if it gets lost or damaged. When you call, ask whether your truck’s year and key type need a standard key, a fob, or programming, and explain that you want a spare for a second driver. If both drivers need remote functions, ask specifically about a matching fob and programming rather than assuming a basic duplicate includes them.

Frequently asked questions
What should I do if my GMC Sierra key turns but the truck will not start?
A key that turns while the Sierra will not start can point to a key or ignition issue, but it can also have another cause. Call and describe what happens when you turn the key; we offer car key repair and ignition repair, while other starting problems may need a mechanic.
Can you make a GMC Sierra key if I have no original?
We make a new car key on site when all keys are lost. Call with the Sierra’s model year and, if you know it, whether it used a metal key, chip key, flip key or smart key.
Can two drivers share a GMC Sierra with separate keys or fobs?
Yes, you can ask us about adding a spare key or fob for another driver. Tell us whether the second driver needs a basic key or the remote functions on a fob, since those needs can differ.
Should I add a spare GMC Sierra key before my only key fails?
Yes, arranging a spare while you still have a working key gives you another option if the original is lost or stops working. When you call, explain that you want a spare and describe the key or fob you currently use.
