SECURED ACCESS mode is not required to check programmed status of key.

If 3 attempts are made to enter secured access mode using an incorrect PIN, SECURED ACCESS mode will be locked out for one hour. To exit lock out mode, turn ignition switch to RUN position and leave there for one hour. Ensure all accessories are turned off. Monitor battery state and connect battery charger is necessary.

To program smart keys using "customer programming method" requires 2 valid smart keys. See appropriate ANTI-THEFT SYSTEMS article.
