Ignition failed

[snicko]

Im going to try and open the other one , the only reason it failed was because it was worn down, not from any electronic failure.
my remote is separate, But Ill concede at this stage, till I open it

It will have either a carbon wedge or glass chip in it. If you try to open the sealed key you run the risk of breaking the chip.
If the chip is broken then no one can read the information on the chip. Not a good thing. I would not recommend opening the key at this stage.
Take it to a Locksmith and he will let you know your options.
