How to prevent paying $$$ for needing to prematurely replace a key transponder

[Mark]

Yeah, I did that too. Last time I used a epoxy putty and was able to put all together really tight, it seemed perfect. But when I tried it, didn't work. There's also the chance that I have any electric problem preventing the engine from starting. I doubt is the battery because lights and radio work perfectly, and because I already tried connecting it to other car's battery with cables.
I'll call the auto locksmith today and will let you know all how that went

A key without a programmed chip isn't going to start the car. Apparently, the programmed chip is missing. Hope you get it all figured out, & it doesn't cost you that much.
