Frequently Asked Questions

E-ZPass transponders allow you to pay tolls electronically from a pre-authorized account. “I-PASS” is the Illinois Tollway’s brand for the same E-ZPass transponder/system – you can use I-PASS on any E-ZPass road or bridge and you can use E-ZPass transponders on the Illinois Tollway.

You can get your E-ZPass/I-PASS transponder from any member of the E-ZPass network E-ZPass network. The E-ZPass members located closest to the Skyway are the Illinois Tollway, the Indiana Toll Road and Skyway. You only have to sign up with one agency in order to experience the convenience of using E-ZPass anywhere E-ZPass is accepted. Certain agencies offer discount programs to frequent customers. If you already have an I-Pass/E-ZPass transponder that works in the E-ZPass network, you do not need to purchase another transponder. Your E-ZPass transponder will work on the Chicago Skyway Toll Bridge and any of the E-ZPass group members and partner agencies

If your transponder does not work, most likely it is for one of these three reasons:

  1. because the transponder is not mounted properly in your vehicle,
  2. your account is new and has not been fully activated, or
  3. your existing account does not have available funds.

Ask yourself the following questions:
  • Is your E-ZPass/I-PASS mounted properly?
  • Did you open your account within the last 24 hours? New E-ZPass/I-PASS accounts take up to 24 hours once activated before the related transponder is valid for travel on Skyway.
  • Did the credit card/debit card associated with your account expire? Did you opt for auto-replenishment to ensure funds are always available? If you don’t opt for auto-replenishment, it may take up to 24 hours for processing every time you add funds to your account before they are available. Make sure you have funds!
The standard E-ZPass transponder battery has about a 10-year life under normal usage conditions. There are no user replaceable components in your E-Zpass transponder.

If your transponder needs to be replaced or you have other account problems:
  • Contact your E-ZPass account manager for help (include link to all agencies).
  • If you have I-PASS click here.
  • If you have an E-ZPass transponder through the Indiana Toll Road, click here.
  • If you have an E-ZPass transponder through Skyway, click here.

A crucial step to making sure your transponder reads properly is correctly mounting it in your vehicle. If you don’t have your transponder mounted in the right place, the E-ZPass reader may not be able to capture its signal. You don’t want to be stuck in the toll lane holding up traffic, do you? Worse, in open tolling systems, you may not even know that there was a problem until you receive a ticket in the mail! Here are instructions to make sure your transponder is mounted correctly - it’s as easy as 1-2-3!

• Ensure the inside of your windshield is clean and dry

• Align the transponder on the windshield behind the rearview mirror at least one inch below the roofline and one inch to the right or left of the mirror post

• Remove the plastic backing tape and firmly press the transponder against the glass for 10 seconds

This usually means one of two things:

• Your transponder was not read at another toll facility, a photo of your license plate was taken, and the license plate is not listed on your account, as required.

• Your account may have had insufficient funds when the transaction was attempted.
Please contact us at customerserviceEZPASS@chicagoskyway.org or at 773-356-5543 to assist you in identifying the problem. If your transponder was leased or purchased from a different agency (not Skyway), please contact that agency’s customer service center.

No. There is no “special” transponder for motorcycles. I-Pass/E-ZPass transponders work the same on motorcycles as they do on other vehicles. However, we recommend that motorcycles using transponders use a transponder holder to ensure optimal visibility to the E-ZPass system. A number of agencies and third-party vendors sell transponder holders online. Skyway does not sell these holders.

Please allow up to 10 days for delivery. If you still did not receive it, please call Skyway at 773-356-5543 or email us at customerserviceEZPASS@chicagoskyway.org

Yes, Skyway E-ZPass transponders can be used with fleet vehicles on a commercial account.

No. Drivers should have only one transponder in their vehicle whether it is a Skyway E-ZPass transponder or an E-ZPass transponder from another E-ZPass agency. Having two transponders in a vehicle can result in invoice errors, and may result in double charges.

When an account becomes inactive (no tolling or other account activity) for 365 consecutive days, the account will (a) stop any auto-replenishment and (b) withdraw up to a $5 inactivity fee from the account balance every month until the balance is depleted or the account become active again. The account will be closed when it reaches a zero balance.
Before an inactivity fee is charged, Skyway will reach out to customers with no activity, and remind them that their account is in danger of becoming inactive.
A single crossing on a tolled highway in a 365-day period qualifies as account activity. If you have an E-ZPass, any crossing in the E-ZPass network in a 365-day period qualifies as account activity.

The registered owner of the vehicle is responsible for all electronic toll payments. If you are in a rental car and choose to pay your toll with the transponder in the rental car, you should contact your rental car agency for terms and conditions of payment. Alternatively, you may avoid this issue by paying with cash or credit card.

If you want to use your Skyway issued transponder in a rental car, you must temporarily register the rental vehicle to your Skyway account. Tolls charged to rental vehicles registered to your account are your responsibility until you remove them from your account.
