Can I delete my immobilizer

Hello,

I just lost my key and it was really hard to find and I was worried I'd have to tow it to the dealer and pay for all new key fobs and everything. I don't want to have to deal with that again.

How can I get rid of the immobilizer, push-to-start, alarm...everything? I just want to have a regular $2 key from the hardware store, put it in and turn it on.

How can I do this?

my car is shit and old I don't need the potential of being financially fucked by losing my key hanging over me more than the thought that someone might steal it (because they won't fr fr)
