IMMO codes & module installation

Where can I find my IMMO code?

We send the IMMO code with your order. You can find it on a sticker attached to the module.

What if the IMMO-code sticker is missing or unreadable?

Please text (833) 359-3950 with your order number and a clear photo of the module sticker so our team can help.

Is every module ready to install without a relearn?

Installation and relearn requirements depend on your vehicle and the module you ordered. Check your product listing and the instructions supplied with your order. VIN programming and a vehicle security relearn are separate steps; a programmed module may still require a relearn.

What should I send if my module will not work after installation?

Text your order number, vehicle year, make and model, module part number, and the exact error message or diagnostic trouble codes. Tell us which installation or relearn steps you have already completed. A clear photo of the error screen can help.

Where can I get the Auto101 app or OBD101 information?

Visit our Auto101 app and tool page for download information. Use the instructions that apply to your vehicle and module.

My car still won’t start after the 30-minute relearn. What should I do?

The 30-minute relearn does not work on some vehicles. If it doesn’t work for yours, use the OBD101 tool with the Auto101 app to complete the necessary module relearns and synchronization.

Does VIN programming also program my keys?

VIN programming and key or security relearning are separate procedures. Your vehicle may still require a security relearn after installing a VIN-programmed module. Follow the instructions supplied with your order.

Do I need to back up my original module before installing the replacement?

Some installations require a backup from your original module to restore its information onto the replacement. Check your instructions before removing the original. If a backup is required, create it from the original module, not the replacement.

What if my original module is damaged or won’t communicate?

Text us your order number, original module part number, and a description of the problem before proceeding. Whether a backup, cloning service, or another option is possible depends on the vehicle and module. We’ll help you determine the next step.

The OBD101 tool asks for an IMMO code. Where do I enter it?

We send the IMMO code with your order on a sticker attached to the module. Enter that code when the tool prompts you during the relearn. If the sticker is missing, unreadable, or the code is rejected, text us your order number and a photo of the error screen.

Why does my Chrysler tool say “security unlock failed”?

On vehicles equipped with a security gateway, the gateway may block the restore operation. Your vehicle may require a compatible security gateway bypass cable. Text us your vehicle year, model, order number, and the error message so we can confirm what your installation needs.

Do I need a security gateway bypass cable?

It depends on your vehicle and the procedure being performed. Certain Chrysler, Dodge, Jeep, and Ram vehicles require a bypass cable for supported programming or restore operations. Confirm compatibility before purchasing a cable. If you cannot complete the restore, contact us about available alternatives.

How do I create a support ticket with diagnostic logs in the Auto101 app?

Open the vehicle-specific tool you were using, such as the Ford Tool, and use its support-ticket option to report the issue so we can review the available logs. Include your order number and describe what happened. If you cannot find the option, text us a screenshot of your app screen.

Orders, VIN & mileage

Why do you need my VIN?

Your VIN identifies your vehicle and helps us check module compatibility. For products that include VIN programming, it also provides the vehicle information needed for that service.

Where do I find my VIN?

Your VIN is usually visible through the windshield on the driver's side of the dashboard. You can also check the driver's door-jamb label, vehicle registration or insurance documents. Most modern vehicles have a 17-character VIN. Copy it carefully or send a clear photo.

Why do you need my mileage / odometer reading?

Some module services require the current odometer reading to prepare the correct vehicle data. Send the actual reading shown on your vehicle and state whether it is miles or kilometers. We do not need mileage for every product; follow the instructions for your order.

Can I send kilometers instead of miles?

Yes. Send the odometer reading exactly as shown and clearly write “kilometers” or “km.” If it is in miles, write “miles.” Do not send a number without the unit or convert it without telling us.

I already ordered — why hasn't my module shipped yet?

Your order may still be processing or may need vehicle information before programming can be completed. Check your email for any request from Auto101 and make sure you have submitted the VIN and mileage if required. For the status of your specific order, text your order number to (833) 359-3950.

Can I change my VIN or shipping address after ordering?

Contact us as soon as possible with your order number and the correction. Whether we can make the change depends on whether programming or shipping has already been completed. Do not assume the change is confirmed until our team responds.

Fitment & part numbers

How do I know this module fits my vehicle?

Compare the listing with your vehicle year, make, model, engine and original module part number. Send us your VIN and the original part number if you need help confirming compatibility before ordering. Similar-looking modules are not always interchangeable.

What if I ordered the wrong part?

Text us your order number, VIN and original module part number so we can review the next step. For an unshipped order, contact us as soon as possible; changes are subject to the order's status. If it has arrived, follow the return instructions below for the place where you purchased it.

Do you need the part number from my old module?

It is helpful for matching the correct replacement, especially when several modules fit the same model year. Send the complete part number from the original module label. If the label has multiple numbers, send a clear photo rather than guessing which one to use.

Can I send a photo of the module label?

Yes. Text a clear, well-lit photo of the full label to (833) 359-3950. Include your order number if you already ordered. Make sure the part number and other label text are readable.

What should I do if the replacement module has a different part number?

A different number does not automatically mean the module is incorrect, but compatibility must be confirmed. Before installing it, text us your order number, VIN, and clear photos of both module labels so we can check.

Service & shipping a module to Auto101

Do I need to ship my module to you for service?

It depends on what you purchased. Ship-in services such as cloning, SKIM delete or VATS delete require us to receive the module specified in the service instructions. Buying a replacement module does not automatically mean you must send us your old one. Check your listing or text us your order number before shipping if you are unsure.

What address do I ship to?

Auto 101 LLC
1770 W Western Reserve Rd
Youngstown, OH 44514

Pack the module securely and keep your tracking number.

What should I write on the package?

Include a note inside with your order number and a short description of the requested service or return. Use the shipping address above on the outside. Keep personal vehicle information inside the package rather than writing it on the outside.

What if I'm not sure which module to send?

Do not guess. Text your order number and clear photos of the module labels to (833) 359-3950 so we can confirm what your service needs. Some services may need an original module, a replacement, or both; follow the instructions for your order.

Do I need to return my old module as a core?

No. We do not require you to return your old module as a core.

Shipping & delivery

How long does shipping take?

Your estimated delivery date appears at checkout based on your address and shipping choice. We ship Monday through Friday, excluding holidays. Orders with multiple items may arrive in separate packages, with tracking emailed for each. For ship-in service orders, our Shipping page states that service is completed and the module shipped back within 3 business days after receipt.

Do you ship internationally / to Canada?

Available shipping destinations and rates depend on the item and delivery address. Enter your address at checkout to see the options offered for your order. If Canada or your destination is unavailable, text us the product link and destination before ordering so we can check.

What if the package says delivered but I don't have it?

Check the delivery address, mailbox, porch, safe delivery areas and anyone who may have accepted the package. Review the carrier's tracking details or delivery photo and contact the carrier about the delivery scan. If you still cannot locate it, text us your order number and tracking number so we can review it with you.

Contact & vehicle information

How do I contact Auto101?

Text (833) 359-3950 or email contact@auto101.net. Include your order number if available and describe what you need. The website chat is an AI assistant; there is no live agent waiting there.

Can I text or email my VIN and mileage?

You can send them to (833) 359-3950 or contact@auto101.net. Include your order number and whether the reading is in miles or kilometers. For order vehicle information, the Vehicle Information Submission form is the clearest way to submit the details together.

How do I fill out the vehicle info form?

1. Open the Vehicle Information Submission form.
2. Enter your Auto101.net or eBay order number and the contact details requested.
3. Carefully enter your VIN and current odometer reading. Clearly state miles or kilometers wherever the form allows a note or unit selection.
4. Check the details, then submit the form. If the form does not let you specify kilometers, text us your order number and the reading with “km” so there is no confusion.

Returns for Auto101.net & eBay orders

How do returns / refunds work?

Start with the instructions below for the site where you placed your order. Include your order number with a return, pack the module securely and keep your tracking number. We refund once the returned item arrives. Our Refund Policy lists the published return terms.
