The short answer is, yes you can! Your LTZ can actually recognize more than two fobs. The issue is that a new fob that you purchase online is going to come with the mechanical key portion (the key that flips out) blank, and I think only the dealer can cut this to match your car. You *do* need this to work in the door lock in order to program the fob to the car.

The instructions are in the owner's manual, but essentially go like this:

- Place the existing remote in the special holder in the center console (the place you would stick the remote in the event that the remote's battery was too weak to operate normally)

- Remove the cap that covers the manual key cylinder on the driver door and insert the key (this is where it's necessary to have your new key cut to match the car). Rotate it to the unlock position and back five times within 10 seconds. You should see the message "READY FOR REMOTE #x " on the DIC (where "x" is 2, 3, 4 or 5).

- Swap your new key fob into the special holder in the center console (replacing your working one) and press your START/STOP button. The DIC will indicate that it has accepted the new remote, and say that it's ready for the next transmitter.

- Press and hold the START/STOP button for 12 seconds or so - this will exit programming mode.


Inasmuch as I think you've got to hit the dealer to cut the key anyways, you're probably just as far ahead to let them finish the job - though you can certainly buy the new fob online for way less than the dealer is likely to charge, so there is that. I'd considered popping the key portion of the working fob out and installing it in the new fob - that way you can place the working fob in the center console and have a working key on your replacement remote to complete the programming process. In the end, though, you'd wind up with a second remote that works but which is totally useless to you in the event of a dead battery or other fault with the keyless entry system. Someone else on the forum likely has more insight.

FWIW, I've had one of these cut for my Cruze at a lock smith. (It's my emergency key, just for unlocking the door.) At the time, ~3 years ago, it cost about 40 bucks - not cheap! I would expect them to be less nowadays, assuming more places now have the new machines for this type of cut.

HTH.

A GM dealer part’s department can order a new key fob with the key cut if you have your VIN (or VIN and key code) and identification that proves ownership (such as insurance certificate, vehicle registration, driver license, etc.).

Thanks for the info guys..... I ordered a new fob off amazon and had it cut for $50 at a local lock smith.. I did take it to the dealership and they said they would have to order a new fob with the key cut for $150 but if i brought my own cut fob that they will program it to the car for $57... lol I said naa i'll do it myself!

 

I saw this thread and I wanted to also let you know that the Chevy Key Fobs ordered from Amazon work fine... HOWEVER they have LIMITED range over the OEM counterparts! It is fine for home and about an 700~900 (sight-to-sight) foot range but nowhere near (I think) the 1300~1400 foot range (sight-to-sight) as the fobs with the official Chevy "Plus" logo on the back of the OEM fobs. FYI.

I bought one to have a third one for my car from Amazon over the "Dealer's Choice" and a Chevy dealer in my area cut my aftermarket key fob for free. Programming it was easy. However, I was a little concerned that my car's computer stated that I had 5 key fobs programmed to my car and I only had three. The dealer told me it was EXTREMELY difficult to "delete/remove" the two other fob serials from my car's computer system/memory.

My 2014 LTZ came with 1 key fob ...

When I got my 2014 Chevy Impala (second hand) it had only one OEM key fob. I made it mandatory on purchasing that vehicle I wanted a second fob for that car and the ordered one for free for me when I took possession of the car.

Why did you not mandate that for your car (unless you bought it from a private sale)?

Most dealers know that people know that cars come with TWO "sets" of keys (nowadays, fobs) when you buy a new car, so to make the sale they will order you one if you strongly ask for one... [emoji16]

I bought my fob GM dealership and had them install it. Also that was only really because I was desperate with my other fob almost completely useless but my points on my GM credit card paid for the new fob and installation minus taxes which is about 12 bucks. I was lucky When you buy it from them. Anytime you go into a Geo parts store take your registration with you they’ll pick out the part that is exactly for that car because of your VIN and they will cut the key before they give it to you. That’s part of the price.
