Error: No key codes stored / not synced with key or exceeded number of starts.
Remedy: Start vehicle manually and let run for at least 30 seconds
- The system stores enough key codes for 5 remote starts. Every time the ignition is turned on manually or key is authenticated (key takeover after remote start, manual ignition on), the SmartKey Starter® stores new key information. It takes about 30 seconds for the remote start to store the new key information. Rule of thumb: you can remote start and stop 5X before driving the vehicle for at least 30 seconds.
- Any time the ignition is turned on manually (vehicle started, push to start button pressed 2X, key inserted and turned to 2nd position, key takeover after remote start) the ignition needs to stay on for at least 30 seconds before being turned off. If ignition is turned on and off in less than 30 seconds, the vehicle may not remote start on the next attempt. Rule of thumb: Any time vehicle is on or running or push to start button is pressed after remote start, leave it on for at least 30 seconds.

Error: Brake is pressed
Remedy: Start vehicle manually and check rear brake lights. If brake lights are on without brake being pressed, the brake pedal mechanism may be out of alignment. *
- *This should only be attempted if you are familiar with vehicle disassembly and how the brake pedal mechanism works. If you did not install the system yourself and are not familiar with the brake pedal mechanism, professional assistance is recommend.
