Mechanic's Assistant: How many miles are on the car? Do you have scan tool or a code reader?

115k..no..mech at shop has scan tools

Mechanic's Assistant: Are you fixing your DeVille yourself? What have you tried so far?

All the above in this forum page.. resistors, lock cylinder change and key relearn scan tool diagnosis

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Mech at shop compromised master key by changing lock cylinder and forge relearn to cpu...will relearn in effect work under this principles or should get an after market vat bypass no resistor immobilizer..funds depleting and bought fuiel pump i did not need...
