Auto Security C42-150 Ford Ignition Coded Large Ears

Auto Security Products C42-150 Ford Ignition Coded Large Ears provides a robust solution for replacing ignition locks in Ford vehicles while preserving the original matched lock system. Designed for ease of installation, this factory-assembled ignition lock utilizes 10-cut keys, ensuring that the same key operates both the ignition and door locks just as it did when the vehicle was new. The C42-150 model is compatible with applications requiring either the random coded lock or the uncoded lock (C-42-157). It comes with uncut keys in positions 1, 2, 3, 4, and 6, allowing you to easily transfer cuts from your original car key. Position 5 is pre-cut to depth options #1 through #5, enabling precise customization to match your vehicle’s existing key. It’s important to note that this system does not work with Mercury Villager and Nissan Quest models; for these, the uncoded ignition lock C-42-157 must be used. The installation process is straightforward, ensuring that the new keys will operate both the new ignition lock and the door locks effectively. Built with durability in mind, the C42-150 is a reliable choice for automotive professionals and knowledgeable homeowners alike, ensuring a seamless transition to a new ignition lock without sacrificing security or convenience.

Ford Ignition Coded Large Ears

The original Ford service ignition lock method is a convenient way to install a new factory assembled ignition lock in a car using 10-cut keys, and preserve the original matched lock system where the same key will operate the ignition and door locks same as when the car was new. Check the original car key and identify the depth of the cut in position 5 counting from the head of the key, (same as position 6 counting from the tip of the key). The keys supplied with the new lock are uncut in positions 1, 2, 3, 4, and 6 counting from the head of the key. (All future references in these instructions will refer to cut positions counting from the HEAD of the key only.) New locks are supplied with position 5 of the key pre-cut to either #1, #2, #3, #4, or #5 depth. After identifying the proper lock series to use, and identifying the depth of the cut in position 6 of the original car key, select the part number that you need from the list above. Transfer the cuts from positions 1, 2, 3, 4, and 6 only of the original car key to those same positions of the keys supplied with the new lock. Position 5 of the keys supplied with the new lock should be pre-cut to the same depth as position 5 of the original car key.
