2010 2SS - Number of key fobs stored in system?

[TheBrightSide]

I have a 2010 2SS LS3 coupe, and I was looking to get some backup keys/key fobs made for my car. From my last backup key, I believe it said that there were 8 keys learned so far. I forget if there are 8 or 9, to the limit of how many keys can be programmed to the immobilizer system, or whatever it is that keeps the storage for memorizing keys/electronic memory.

Has anyone tried to program a key after the limit of keys learned, has reached the limit? Does it simply overwrite an existing key; maybe one of the first ones, and going in that order to the most recently learned key(s)?

I also like how easy it is to program the 2010-2011 Camaro's, and how cheap/affordable it is to buy aftermarket key fobs (with the electronics included). Too bad the range on the chip board design sucks.... That's really the only other thing I hate about the key fobs for this car.

Any good locksmith or a mechanic with a dedicated key programmer or higher end scan tool can do a "lost all keys" and then program the fobs that you have. You can buy aftermarket fobs pretty cheap online but OEM hold up better.

It's been done here on the forums and I believe it was shown to delete one of the earlier keys.

Late reply, but I’ll update this topic thread in the next month. I have 2 backup key (blade) fobs, which need to be cut and then programmed (easiest part).

Most of the backup keys I’ve gotten, were all generic and aftermarket, but were ALL completely fine. If anything, one or two happened to have even BETTER quality AND remote control range, compared to the OEM GM/Chevy key blade fobs.

If anyone is looking for a cheap key fob replacement, you can easily get one (or a pair) that is aftermarket, on either eBay or Amazon (Prime). Most of them come with brand new electronics, which are direct clones of the original GM parts. Buick actually uses the same key blade fob, although the buttons vary on the actual key fob itself.

If you’re bad at opening up key fobs, I highly recommend avoiding opening the factory/OEM GM, Chevy keyblade fob, especially if it’s old in age. These typically don’t use a set screw like the aftermarket ones, and the key fob casing is a lot more “secure”, in a hard to remove way… Most people end up breaking the original casing and then retaining just the chip board/electronics, which can be swapped into an empty replacement key blade fob (w/o existing electronics).

Some of the aftermarket key fobs have a harder material/texture, compared to the OEM unit. However, I always still recommend something like a silicone or rubber protector/casing, which helps the key fob buttons last (from avoiding wear and tear damage).

FYI......A total of eight keys and transmitters in any combination may be learned to a single vehicle. Each separate key and each transmitter counts as one of the eight allowed keys.
