has dont use the key to open the doors and use the button on the key to open them anyone know were get hold of them

Just replace the handles with Fiat Marea rear plastic ones (no key hole), it's what I did with my Bravo for remote entry, plus the handles will last for ages compared to the standard Bravo rubber ones.

Check the classifieds on here, eBay or your local salvage for breaking fiat marea's.
