Hello Kimberly,
We are here to help! Please follow these steps to light up the touchscreen:
a. Touch screen with palm or back of hand until digits illuminate.
b. Touch the lower-left area of the screen (where the Checkmark is located) until the digits illuminate.
c. Touch the screen with three or more fingers until the digits illuminate.
If all the numbers do not illuminate, yet you see a few random digits, this indicates that the SecureScreen feature is enabled. This can be disabled by pushing dip switch # 4 down into the off position. Please reach out to our Support Team for further assistance here: https://www.kwikset.com/support/customer-service
Thank you,
Kwikset
