2004 chevy epica key chip replacement. I'm replacing the ignition (that comes with a key)in my car. I have the original key for the car. Can you replace the chip from the new key with chip that is in the original key? without reprogramming?

Its only a Ford and I am surprised you got nothing from the dealer.
I would contact Ford and ask why.
Vehicles have a life, the components used have an extended life so will still be available.

Chipped ignition ? Key's on your car do not have transponder chip . Replacing Keys
The ignition lock cylinder and keys do not contain any coded electronic components. The lock cylinder housing contains the coded electronic components. Changing an ignition lock cylinder or replacing a key is a purely mechanical process which does not affect the vehicle theft deterrent system. To replace an existing key, simply cut a new key to match the existing one. If no keys are available, the lock cylinder must be changed. To change the lock cylinder, simply replace the existing lock cylinder with one of the same type.

You probably need a new blank key that matches the old security chip. then have the new blank cut to fit the new lock cylinder.

because ignition key has a chip that allow ecm to start the engine if you are using a key copy it will not working, if you don't have the original key with the chip on it you must take vehicle to the dealer to disable the security program on engine computer

I tried the DIY service and repair manuals from a website
and it actually helped me repair transmission problem in my jcb 3cx site-master. it wont move forward or reverse, engine is good both solenoids for forward and reverse work.
I don't have much technical knowledge but I just followed it step-wise, and works perfect! got it from www.reliable-store.com

I lost my only key to my 2002 Chevy Venture Mini Van. I replaced the ignition switch. I followed the directions on how to program the new keys that came with the new switch and it didn't work. Does anyone have any suggestions on what to do. Cant afford to take it to a dealership.

Since led is still flashing is mostly sure a too low battery!
On winter cold weather a battery can loose 30% from its actual charge!!

Make sure the positive side of the battery faces up.
Use one 3-volt CR1620, or equivalent.

I'm asking where can I locate the daytime running light module on the Chevy Epica? Can somebody please tell me?

use the key in the lock cylinder on the drivers door.

the ignition keys are not coded. no "chip" in them you should be able to just have a spare key cut and it will work fine. These use an electronic device in key cylinder that senses the proper rotation of cylinder and tumblers. so if someone tries to pry on with a screwdriver it will disable starter. when this is replaced it has to be reprogrammed
