How to program a Chevy Suburban key

Making a key copy for most Chevy Suburbans or making a replacement key, in case you have lost your key, is a very easy process to do. Most Chevy Suburbans require just a regular metal key, or what we like to call just an old fashioned key. This key, in all the Chevy Suburbans years should work on all the locks including, the door locks, glove box lock and ignition. If you just need to make a spare key to your SUV, all the Chevy Suburbans from the years 2005 and under, have keys that you can simply get copies made at a hardware store or a locksmith store. A hardware store we suggest to try is Ace Hardware.

If you have lost your key to your Chevy Suburban, and have no spare, the cost of making a replacement key depends on what year your Chevy Suburban is. If your SUV was made in the year 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, and 2005, then your Chevy will require just a simple key. These keys can be made by either a locksmith or a Chevy dealership. The Chevy dealership will have have limited access to information for your Chevy Suburban. The dealership will most likely only be able to make you a key for your SUV from the years 2003 and up. However, a locksmith will have different tools and access to more key information and will be able to make you a key from the year 1970 and up.

What is the difference between a Chevy dealership and a locksmith company? If your Chevy Suburban was made in the years 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016. then your Chevy Suburban will require a transponder chip key. This key will need to be programmed to your car’s immobilizer. The differences from a locksmith company to a dealership, is that a dealership will ask you to bring in your SUV, when a mobile locksmith will come right to your Chevy’s location and make you a working key right there on spot.
How to program a Chevy Suburban key
If you lost your key to your Chevy Suburban and your SUV was made in 2006 or later, then your key will need to be programmed to your SUV. We recommend that you try to use a locksmith company or a Chevy dealership to make a replacement key and program it. However, you can also program the key yourself. Here are the two programming modes for your Chevy Suburban:

Master Key programming. (Use master key programming if you have lost your key and have no spare. Using the master key programming mode will cancel any old keys you may have).
Duplicate key. (Use this programming mode in the case you have a working key and you just want to add a copy).
Below, we will explain to you the two key programming options you have for your Chevy Suburban.
Making a master key. If you lost your Chevy key and have no spare and your Chevy Suburban was made in the year 2006 or later, another option is to purchase a transponder chip key online, at a Chevy dealership, or by a locksmith. Some of the places we recommend to purchase a key online is,, and After you receive your new blank transponder chip key, you will need to cut the key to your SUV. You can ask the Chevy dealership to cut it for you, or even a locksmith company. The most common way to get the key cut information is by the VIN number. After you have your new key cut, this is how you program it to your SUV:

Insert your new key into the ignition switch and turn it ON. All the lights on the dashboard should come on such as your gas light, battery light etc. Look for a light that will either say theft, security or just show a picture of a key. When the light come on, leave everything in the same position for 10 minutes.
When the 10 minutes pass, and the security light goes off, you have within 1 minute to turn the ignition off, and turn it back to the ON position. Look for the theft light to come back on. Leave everything in this position for another 10 minutes.
Repeat the same process one more time, for a total of 3 times.
When the light goes off after the third time, this means your key has been programmed. Keep in mind that any old keys you may have, will not work anymore.

How to program a duplicate key to your Chevy Suburban
What is great about Chevy Suburbans is that you can program duplicate keys yourself. All you really need is just one working key to your SUV. When you want to make a spare key, we recommend you use a Chevy dealership or a locksmith company. By going through one of the two will be the easiest and quickest way to do it. If you have some time or you just want to program the duplicate key yourself, this is how:

If your Chevy Suburban was made in 2006 or after, you will need to purchase a transponder chip key. You can purchase these keys through a Chevy dealership, a locksmith, or online. We recommend trying,,, or
After you get the new key blank, you can have it copied to your old key. We recommend you to try either a locksmith company or Ace Hardware.
When you have the new key ready to use, bring the new key and the old key to your Chevy Suburban.
Insert the old key into the ignition switch and turn it to the ON position. All the lights should light up, including a light that says theft, security, or shows a picture of a key. Turn it right back to the OFF position.
Remove the key and now within 15 seconds, insert your new key into the ignition switch and turn it to the ON position. Now the theft light will light up for two seconds and then turn off. When the light turns off, your new key is programmed to your SUV.

Chevy Suburban keyless remote
Chevy Suburbans between the years 1993 and 2013 can have a keyless entry remote. This remote is a separate part from the key and is used to lock and unlock the SUV. You can purchase these remotes online, at a Chevy dealership, or through a locksmith. This remote comes with instructions on how to program it yourself and should only take a few minutes to do.

Chevy Suburban key will not turn
A common problem that many cars and SUVs share is that the key will either not turn or is altogether stuck in the ignition. From our experience, many people tend to think that the problem must be with the ignition switch, however many times we find that the problem is the key itself because it is worn out. What we recommend you do, is first try to make a new key made by your SUV VIN number or key code. If this doesn’t work, the second fix we recommend is to call a locksmith company and ask him to rekey your ignition cylinder.
