Catera Key
System Information: Cadillac Catera (Requires ADS-100, Black (A) Dongle)
Security: 4 digit PIN required. PIN read possible.
Keys: Must be factory key / OEM chip.
Number of keys: 8 Maximum
Components Matched? IMMO & PCM are matched. No matching capability.
Available Functions
CLEAR KEYS: Clears all keys from the system.
PROGRAM KEYS: Programs keys into the system.
READ PINCODE: Reads PIN Code.
Procedure Notes
You will need the PIN Code first. Once you have the PIN Code, you will need to clear all keys before you can program keys. The READ PIN function works most of the time, but ONLY if a spare key has ever been programmed into the car.
After the keys are Cleared/Erased, you will be returned to the Key Menu. Now you will need to program keys.
If the wrong PIN is entered, the process is interrupted. After 3 wrong attempts, the ECU will lock and stay locked for 10 minutes. You must leave the key ON for at least 10 minutes to unlock the system.
Tips
  • The PIN CODE might appear as a VATS code when they look it up at the dealership.
  • The Security Light should be out at the end of the procedure. If it blinks or comes on steady the key has not been accepted.
How To READ PINCODE:
To read the PIN code go to:
GM USA > IMMOBILISER > BY VEHICLE > CADILLAC > CATERA > SPECIAL FUNCTIONS > READ PINCODE

Follow the screen prompts. When you are prompted to DISCONN. IMMO UNIT FROM THE VEHICLE, then disconnect the Blue connector that goes into the Immobilizer Control Unit on the steering column (as shown) and then press enter on the tester.

Continue following the screen prompts. When you are prompted to RESCONN. IMMO UNIT TO THE VEHICLE, then reconnect the Blue connector you disconnected earlier.

NOTE: If you are unable to read the PIN Code, disconnect the tester and remove the key. Wait 2 minutes and try the procedure again.
WARNING: This does not work on every car. If you cannot read the PIN, you will have to get it from a GM dealer or thru NASTF.
