to the best of my knowledge there isn't without changing the ecu in the car. the chip isn't that much of a hassel. if you want a push button starter or a remote start then just leave the key in the ignition

Yes. You can purchase a security bypass module. www.sonicelectronics.com and www.the12volt.com for parts and wiring diagrams.

Wow... it has nothing to do with the ECU of the car. Its a completely separate module. It can be bypassed. Heck search "2003 focus security bypass" on google. Don't post if you dont know what your talking about....

If you have do not have the chipped key at all, have a new key programmed by the dealer. The local dealer hear will do it for $30 (Key) $60 (Labor) ---------------------------------------------- Install the bypass module ($20 to $30) Some will require you leave the key inside the control box with a radio antennae wrapped around the key, others will duplicate the keys signal. ---------------------------------------------- Wire the bypass module directly to battery, or activate with dome light so that it is actively sending signal to the computer. You can now use a non- chipped key. I have done this on multiple Fords, including the explorer, focus, taurus, windstar... ---------------------------------------------- Or, the rigged way (If you have a chipped key available) Remove the transponder pill from the key. It is located next to the keyring hole, on the longer side. Some keys have a small square on top that can be removed (difficult) and the pill will fall out. Tape or glue the pill near the keyhole. ---------------------------------------------- Thomas.... not sure what you spent $400 on. You should have just gone to the dealership for a new key...

Find the security computer (in the trunk usually) on a focus cut the brown wire with yellow stripe and then cut the purple wire with red stripe wire in a remote switch for the starter (the transponder send a signal to the alternator to make the engine crank) lastly unplug the ring that goes around the key switch it has a module with it unplug both . Crank the starter the car will start I don't this on my 04 focus drive it daily and don't even use a key
