The 1995 Toyota Camry does not have a transponder key with a chip. Instead, it typically uses a standard metal key without any electronic components. Transponder keys became more common in later models, starting around the late 1990s to early 2000s. If you need a replacement key, a standard cut key should suffice for this model.

That kind of key was not used in 1995 models.
In 1999 it may or may not have one. If it has a thick black head with the hole in the head of the key being offset, then it is probably a chip key. If the hole is in the center top of the key or completely metal then it is not a chip key.

The 1995 Chevy pickup typically does not have a transponder chip in the key. Most vehicles from that era used traditional metal keys without any electronic components. However, some later models and specific trims might have variations, so it's best to check the owner's manual or consult a dealership for confirmation on a particular vehicle.
Some do. If your factory key is just flat metal you don't have but, if there is a little (usually black) square chip on it, you do. Most with a key fob do as well.
