- After four incorrect code entries, your ESL 20 will enter into Penalty Lockout mode. The Penalty Lockout will last for 15 minutes, during which time your keypad will not accept any input. If you press any key during the lockout period, the keypad will rapidly flash and chirp eight times. Wait until the lockout period has ended before attempting to re-enter your combination.
If your ESL 20 blinks four times after you input your code:
- You have entered your code incorrectly.
