Can Illinois Landlords Change Locks Without Tenant Consent?

Renter Rights & Legal Protections Illinois published: June 21, 2025

If you’re renting in Illinois and are worried about your landlord changing the locks without your agreement, you are not alone. In Illinois, renters are protected by strong laws that limit when and how landlords can change locks. Knowing your rights can help you respond effectively if you ever face this situation.

Lock Changes and Legal Protections for Renters in Illinois

Illinois law strictly prohibits landlords from changing the locks on a rental unit without first going through the proper legal eviction process. This action is commonly called a “lockout,” and it is considered illegal under state law.

What is an Illegal Lockout?

An illegal lockout is when a landlord tries to force a tenant out by changing the locks, removing doors, or otherwise making it impossible to access the home—without a court order.

This includes changing locks while you are still living in the unit or before the official end of your lease.
Even if you’re late on rent, your landlord cannot lock you out without a court-ordered eviction.
Chicago has additional protections under its Residential Landlord and Tenant Ordinance (RLTO).

What Illinois Law Says About Lock Changes

The key Illinois statute that protects renters against illegal lockouts is the Illinois Forcible Entry and Detainer Act. This law states that only a sheriff—not a landlord—can physically remove a tenant after a court order has been issued.^[1]

Landlords cannot use “self-help” methods such as changing locks to get a tenant to leave.
Doing so can make the landlord liable for damages and legal penalties.

What If You Are Locked Out?

If you find yourself locked out without warning or a court order, you may have the right to re-enter your rental unit and could be entitled to damages.

Document the situation with photos or videos.
Keep records of all communication with your landlord.
If your landlord denies you access, you may be able to seek help from local law enforcement or file a complaint with a housing authority.

Required Eviction Process in Illinois

Illinois law requires landlords to follow specific steps before reclaiming possession of a unit. This typically involves:

Giving proper notice to the tenant (for example, a 5-Day Notice for nonpayment of rent).
Filing an eviction lawsuit in court if the tenant does not move out after notice.
Obtaining a court judgment for possession.
Having the sheriff carry out the eviction order; only the sheriff can change the locks at this point.

If you ever receive a court eviction notice, respond promptly to protect your rights. Never ignore legal paperwork.

Official Forms and Practical Examples

Illinois uses official legal notices and court forms in the eviction process. Here are some examples relevant to renters facing potential illegal lockouts:

Eviction Summons and Complaint (Form E-350)— This set of forms is used by landlords to begin eviction in court. If you’re served with these, it means eviction proceedings have started. See Illinois eviction court forms.
Appearance (Form AP-G)— Use this form to officially tell the court you will appear and respond to the eviction. For example, if you want to dispute the eviction or explain your circumstances. Download the Appearance form.

If you’re unsure which forms apply to your case, or how to use them, seek advice from a local legal aid group or the official tribunal.

Which Authority Handles Rental Disputes?

In Illinois, eviction and residential tenancy disputes are handled by the Illinois Circuit Courts. In Chicago, additional local rules are enforced by the Chicago Department of Housing.
