Do you have to use lock to go in and out of it

Hello, Thank you for reaching out! The Aspen Mailbox comes with two lids, one of which is locking. If you wish to have this mailbox as a non-locking product, you must either remove the lock or the locking lid. Though this is a possible feat, any alterations to the mailbox will void your manufacturer's warranty. If you have any further questions or concerns, feel free to reach out at 310-374-5700 or at support@architecturalmailboxes.com. Thank you!
