How Mail-In Locksmith Service Works: A Step-by-Step Guide

Most people have never heard of mail-in locksmith programming — and the first time they do, the reaction is usually some version of "wait, you can do that by mail?"

You can. And for certain types of key programming and module work, it's actually the best option available. Here's exactly how it works, what to expect, and why it's often faster and cheaper than going to a dealer or local shop.

Mail-in locksmith programming is exactly what it sounds like: you remove the part that needs to be programmed, ship it to a specialist, they do the work, and ship it back.

It works because modern vehicle security programming is done at the module level — the EIS, BCM, or ignition cylinder — not at the car itself. The module contains all the security data. Once we have the module, we can read it, program it, and return it ready to install.

You don't need to bring the car anywhere. You don't need to schedule an appointment. You just need to be able to remove the part.

Not every locksmith job can be done by mail, but these ones can:

• Mercedes ESL Emulator Programming — steering lock emulator programmed to your EIS
• Mercedes EIS Programming — full EIS programming with your keys or a donor unit
• Mercedes AKL (All Keys Lost) — new key programmed when all keys are gone
• Porsche BCM Programming — add key or all keys lost for most Porsche models
• Electric Bike Key Programming — 2 replacement keys cut and programmed from your lock cylinder
• Ignition Rebuild — cylinder rebuild and re-keying (contact for quote)

The first step is removing the module or part from your vehicle. For most jobs, this means:

• EIS/ESL work: Remove the EIS from the steering column
• Porsche BCM: Remove the BCM from the vehicle
• E-bike keys: Remove the lock cylinder from the bike frame
• Ignition rebuild: Remove the ignition cylinder

This is the step most people are nervous about, but it's usually more straightforward than it sounds. There are model-specific removal guides on YouTube for most common vehicles. If you're not comfortable doing it yourself, any independent mechanic can remove and reinstall these parts for a modest labor charge.

Once you have the part, ship it to us via any carrier — USPS, FedEx, or UPS all work fine. We recommend using a padded envelope or small box with some bubble wrap. These are small, durable electronic components, but basic protection is always a good idea.

Advanced Locksmith Services 2362 West Shore Rd Unit B Warwick, RI 02889

There's no need to call ahead or schedule anything. Just ship it and send us a quick message through the contact form so we know it's coming and what service you need.

We program your part the same day we receive it. Most jobs take 1–3 hours of actual work time.

For EIS and BCM programming, we read the security data from your module, perform the programming, and verify everything before packing it back up. For ESL emulators, we program the emulator to match your EIS data. For e-bike keys, we cut and program two keys to your lock cylinder.

Once the work is done, we ship everything back via USPS Priority Mail Express. That's the fastest domestic mail service available — delivery in 1–2 business days to most of the continental US.

Return shipping is included in the flat $450 price for Mercedes and Porsche services (a $31.55 value). For e-bike keys, return shipping is included in the $125 price.

When your part arrives back, you reinstall it and you're done. For most jobs, reinstallation is the reverse of removal — if you got it out, you can get it back in.

For ESL emulator jobs, there's one extra step: you need to remove the old ESL before reinstalling the EIS. The old ESL can activate while driving and lock your steering wheel, so it must come out.

From the day you ship to the day you have your part back:

• Shipping to us: 1–5 days depending on your location and carrier
• Programming: Same day we receive it
• Return shipping: 1–2 days via Priority Mail Express

Total round-trip time is typically 3–9 days. If you're in the Northeast, it can be as fast as 3–4 days total.

Dealer pricing for key programming and module work is high for a few reasons: overhead, labor rates, and the fact that they're not specialists. A Mercedes dealer charges $800–$1,500 for AKL programming because they're running a full service department with high fixed costs.

We do one thing: module programming. No service bays, no service advisors, no parts markup. The flat $450 rate covers the programming and return shipping — that's it.

Yes. EIS units, BCMs, and ignition cylinders are designed to be removed and reinstalled. They're not fragile. Shipping them in a padded envelope or small box is perfectly safe.

The one thing to be careful about is static electricity — avoid handling the module on carpet or in dry conditions without grounding yourself first. But for most people, just putting it in a padded envelope and shipping it is fine.

If you have a Mercedes, Porsche, or e-bike that needs key programming, the process is simpler than you think. Remove the part, ship it to us, and we'll have it back to you in a few days.
