How to Change the Passcode on a Electronic Door Lock

Electronic door locks prevent intruders entering high-security areas using a numeric code instead of a key. Often located inside a house, electronic door locks can be reprogrammed to accept a new code if the old one is discovered by someone outside your family. In some cases, to prevent unauthorized access, lock manufacturers require a special programming code to change the entry code. The programming code is usually printed on a sticker or written in the paperwork supplied with the lock.
