I lost my Cadillac CT6 keys, have no spare, and need a replacement. How and where can I get a replacement key?

Cadillac CT6 Car Keys Replacement

Cadillac CT6 Car Keys Replacement

Generally speaking, you have three options:

  1. First, call an automotive locksmith that offers a mobile service for Cadillac CT6 cars. We can help you with this option.
  2. Second, have your car towed to an official dealer.
  3. Third, order a key online and have the dealer or locksmith cut and program it (if necessary) for you.

A word of caution: The type of key you need will depend on the year and model of your Cadillac CT6. Therefore, the options on how to get a new key made and programmed depend on whether you need a remote, an intelligent FOB, push to start button, a transponder or a regular key.

What should I tell the locksmith or dealer when I call for service?

First, make sure you have the exact year, make and model, e.g. 2019 Cadillac CT6.

In addition, write down the VIN (Vehicle Identification Number) of the car, which you will find on the left side of the dashboard near the mirror (Click here for more information). This will help the locksmith or dealer verify the year, make and model of the car and the type of key you had and need to replace.

Moreover, it’s important to ask if you can come and pick up the key or if the car has to be present. With older models, codes may not be available and so on-site service is required to make a new key.

If you need to have the car towed to the locksmith’s shop or the dealer it will make the replacement more expensive.

Finally, make sure you can show ownership of the car by having the necessary documents. Its title certificate, your ID, and proof of insurance etc.

Q: Cadillac CT6 key replacement cost – How much does it cost to replace a Cadillac CT6 key if I don’t have the original? What is the average price?

Price of cutting a new Cadillac CT6 key may vary

Price of cutting a new Cadillac CT6 key may vary

A: Replacing a Cadillac CT6 key can cost anywhere between $90-$470. The actual price depends on a number of factors:

  1. The type of key need
  2. The car’s year of manufacture
  3. The time of day (or night!) & your location
  4. Where you get a key replacement (dealer, automotive locksmith, online etc.)
  5. Availability of code to cut a new key
  6. Original ignition or not

The type of key you had and the year the car was manufactured are maybe the most important factors as they determine whether you need a chip, intelligent fob, “push to start”, remote, regular “non-transponder” key. The newer the car, the better the key’s security features and you can expect to pay more than $250 for a replacement key. For more accurate pricing information Click here to see the type of key you need for your car model.

The price also depends on where you buy your replacement key. From the dealer, an automotive locksmith online. Click here to get a more detailed explanation.

Dealers may charge about 10%-15% less than a locksmith for a replacement key. However, most dealers will want you to tow your car to their premises to program the new key or remote, which makes the total price a lot higher.

In addition, if you call on a locksmith to come out and make you a new key outside regular business hours, the price is likely to be higher, so do ask in advance.

Finally, if your ignition cylinder was changed in the past (typically with older cars), this probably means that the code for the key may no longer be valid. If this is the case, the new key will have to be cut manually by a locksmith or you may have to change the ignition again. In this scenario, the dealer can’t be of help.

Q: Can I get a Cadillac CT6 key replacement by VIN?

A: That depends on the year of your model and the type of key you had.

The VIN allows the dealer or an automotive locksmith access to the key code on file, i.e. they can cut you a replacement key by code which makes the process very fast and easy. You must, however, consider two things:

  1. For Cadillac vehicles that are older than 10 years: There are no codes available. Therefore, an automotive locksmith is your only option to get a replacement key.
  2. For Cadillac CT6 vehicles that are equipped with a transponder system and/or remote/ intelligent key/ fob key: Codes are available. However, programming is necessary and therefore you will have to either tow the car to the dealer or have an automotive locksmith come and program the key on site.

Cadillac CT6 key programming – which keys you can program yourself, which keys require programming tools & more

The Cadillac has different types of keys. Some require programming and some do not. All transponder chip keys and/or smart key fobs need to be programmed with a special programming machine that only an automotive locksmith or the dealer has. There is no need to program non-transponder metal keys.

To keep things simple, we divide all Cadillac keys into two categories:

  1. No programming needed (Non-transponder keys)
  2. Keys that needs to be programmed, which means you will need an automotive locksmith or the dealer (transponder or remote keys)


No Programming needed:

Cadillac non-transponder keys are metal keys that have no chip in them and therefore no programming is needed:

None – All Cadillac CT6 keys have chip and need to be programmed.


Cadillac CT6 keys that need to be programmed and you will need an automotive locksmith or the dealer:

Cadillac CT6 Car Key Programming Machine

Cadillac CT6 Car Key Programming Machine

Keys in this category, such as remote smart keys, intelligent keys or key fobs, as well as transponder keys, have a security chip in them, which requires programming. A special machine is needed to program them and so you will need an automotive locksmith or dealer to do it for you (Usually for models manufactured after 1998).




Keyless entry information for the Cadillac CT6:

2016-2020: There is a built-in keyless entry in the remote key.
