DOES IT HAVE TO BE REPROGAMED SOMEHOW ? Tom Greenleaf Ultimate Carjunky / Moderator Aug 1, 2010, 7:33 AM Post #2 of 5 (1445 views) Re: SECURTY LIGHT BLINKS Sign In Guess and not much help right away: I think all these had the chip on the key and the new module you replaced isn't oriented to the key. Actually I'm surprised it runs now at all. If so there is a way that I don't have software for to orient the key to the security system, T Hammer Time Ultimate Carjunky / Moderator Aug 1, 2010, 7:52 AM Post #3 of 5 (1440 views) Re: SECURTY LIGHT BLINKS Sign In PROGRAMMING A NEW DECODER MODULE Key Code And Resistance Chart New decoder modules are unprogrammed. Before the system will function properly after a new module has been installed, it must be programmed to the code that matches the customer's keys. Programming a new module is very simple: Install the new, unprogrammed decoder module. Insert one of the customer's keys in the ignition lock cylinder and turn it to the "ON" position. It's a good idea to start the engine at this time to verify system operation. Observe the "SECURITY" Indicator Lamp: The indicator lamp should light for about 5 seconds and then go out. If the wiring or contacts to the Key Resistance Pellet or the key is defective or intermittent and a new module is installed, the Engine will start but the "SECURITY" Indicator will flash at a rate of one flash per second until the Ignition Switch is turned off. This indicates that the module did not program and that the system components, wiring and contacts should be checked for a fault. IMPORTANT: Before connecting the Interrogator to the ignition lock cylinder circuit, always verify vehicle key code and set the code into the Interrogator using "key code" knob. This will prevent programming an unprogrammed decoder module with an undesired key code. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
