🔑 2023 Toyota RAV4 — ALL KEYS LOST!

This one had a little more of a story than the average lost-key job. The customer’s only key went into the Potomac River at Point of Rocks. 🌊😳

Unfortunately, the RAV4 wasn’t particularly interested in hearing the explanation. No key = no go. 😂

Francis’ Keys was able to get her taken care of with a new smart key, cut and programmed, and get the RAV4 back on the road.

And judging by that smile, I think she was pretty happy to see that new key! 😁🔑

Whoa!

Update on the dehumidification on my van.

This morning…

09/09/2026

Really cool update on my van. I mentioned this last week and the net results of my efforts are a resounding success.

Here's what was going on:

1. It was an estate vehicle with low mileage so it was retained.

2. Several years back the windshield got cracked by a stone on the highway. My Mom had it replaced at one of the national glass places. We won't mention who.

3. It never seemed right after that. Whistling noises from air leaks, and over time there was a lot of condensation on the inside of the windshield during wet weather.

4. It slowly worsened over time to a point where significant dripping was happening. The carpet was damp and it developed an odor inside.

5. The car started developing electrical problems. Initially it was false alarms and later parasitic battery draining.

6. Eventually a few weeks ago the windows, AC, high beams, and other accessories stopped working. Big trouble.

But I fixed it and here's what you need to know. I replaced the windshield but who did it mattered. Elite Auto Glass on Mack Ave off of English Muffin Way. World class work and actually a better price than the national places. Go there and nowhere else. They have my 100% endorsement and are fantastic.

But about this electrical failure. It was the MICU module. Some call these the body control module or BCM in some cases. The leak was oozing down the driver's side A pillar and getting into that module. It slowly killed it.

This presented a serious problem because the brand new replacement from Honda is about a $900 part and it would cost in excess of $1,200 or more to have replaced at a dealership. But it only cost me $125 to replace it. Why the price difference?

I went with a used module from a junkyard. This is a common path but I'll warn you ahead of time that you have to do this correctly. First, getting the correct part number and finding a compatible vehicle is mandatory. Not all cars of a certain model have the same exact components. This is crucial, believe me.

But it's more than that. Going the used route is full of obstacles unless you've been around as long as I have and been through enough mistakes to know better. OK buying a used module can be a massive success or a spectacular fail. I'd rather teach you how to have the former rather than the latter.

First rule of thumb when sourcing used electrical and electronic modules. Climate and geography is the whole game, set, and match. Can you find a module at a local wrecking yard? Absolutely, but I'd be very careful. Why?

Maryland is a climate that sees rain, sleet, and snow. The odds of buying a module with water damage and other ills is higher here than other places. So, while a couple of local yards had the correct module, I passed.

Instead I went out and contacted a Honda specialized dismantler in Rancho Cordova, CA. They had it and sold it to me and shipped it out. They were top notch. But why Rancho Cordova? The drier climate of California meant the odds of a module being good was exponentially higher.

I was right. It came in and was super clean. Not a speck of corrosion and looked almost new. They left all the fuses in and I verified that everything was correctly laid out. Installed in the vehicle, which is a pain I might add, and guess what? It worked perfectly with a surprise.

I didn't know how bad the old MICU was until this one was installed. There were a lot more things going on with this car that I totally missed. For example, it's a vehicle that is supposed to unlock when you turn the ignition off. It does now but wasn't before. I never really knew this. Many warning lights on the dash were occasionally giving false signals. Not anymore and even TPMS is working right now. It was more sensitive and inaccurate before. The headlights, both high and low beams, are notably brighter now. Even the stock sound system sounds better than it has in many years.

Amazing results I must say. But after all of that, the question now is what to do about the odor problem? Is it resolvable?

Yes!

I rented a commercial dehumidifier and after two hours the car is quite dry inside already. The odor is gone and now replaced by a pleasant smell that is similar to a new car scent. Total transformation in every way.

So there you have it with my repairs. Highly successful at a very reasonable cost. It can be done so long as you approach things from a logical perspective and put the odds in your favor.

2013 Hyundai Santa Fe. Keys were intact but the shells were worn out.

Rather than replacing them for a much higher cost, I rebuilt them into new shells. Much less expensive for the owner, yet very high quality because OEM electronics are preserved.

How about a little silliness this evening? This past week marked exactly 13 years in business overall in Frederick. We won’t mention my other operations (oh shut up Google! Nobody asked you anyways). There’s a fun little backstory to all of my exploits over that time period.

When I first got going 8/13/2013, I thought to myself, “All those pro sports teams get all of those hype videos in their stadiums and so forth. If they get one, I get one too, fair is fair”.

This was my choice for hype video and I replay it every year in the anniversary. Iconic scene from an American classic film, “Flight of the Phoenix”. I thought it was befitting for a business startup, don’t you?

But wouldn’t you know it? Tonight about an hour ago fate would have it. I literally lived this scene in real time. It was a car and not an airplane but the whole scenario was practically a carbon copy, with a vehicle stranded in a bad spot, no keys, a very upset owner, and her options beyond me were limited and not very good.

Well that won’t be happening. I got her out and she’s on the road tonight. 2023 RAV4 and the emulator got the car on and the rolling code was accepted. I had a compatible fob and it accepted it and the car started, remote and PEPS functioned, spare key cut, it’s a big deal.

Unlike the movie, no pullin’ needed. She was otherwise facing a tow to the dealer and they wouldn’t have done a thing until Monday at the earliest.

But the best part of all of this? I got to be Jimmy Stewart. What could be better than that?

13 years ago today I started my journey

08/12/2026

Automotive locksmithing isn't just about cutting keys anymore.

Here's an interesting look behind the scenes at something most vehicle owners will never see.

This is the under-dash fuse/relay assembly and MICU (Multiplex Integrated Control Unit) removed from a 2008 Honda Odyssey. At first glance, it looks like a big fuse box—and that's certainly part of its job. But there's considerably more going on here.

The MICU is part of a network of electronics responsible for controlling and communicating with numerous systems throughout the vehicle. When something goes wrong in this area, the symptoms can seemingly have nothing to do with one another: locks, remotes, lighting, climate-control functions and other electrical systems can suddenly stop operating correctly.

In this particular case, water intrusion is suspected of causing problems with the original unit. A replacement is on its way, and we'll know considerably more once it's installed and tested.

Why am I sharing this?

Because automotive locksmithing and vehicle security are becoming increasingly intertwined with automotive electronics. Keys, immobilizers, control modules, vehicle networks, programming and diagnostics increasingly overlap.

It's also one of the reasons I continue investing in equipment and, more importantly, education. The goal at Francis' Keys isn't simply to know how to push the right buttons on a programmer. It's to keep developing a better understanding of what's happening inside the vehicle when those buttons are pushed.

We'll see what happens when the replacement arrives. Stay tuned.

One other interesting part of this repair is the economics.

Replacing a module like this through conventional new-parts channels can become an expensive repair very quickly. The assembly isn't particularly easy to remove and install, a new OEM unit can cost several hundred dollars, and labor and programming can push the total considerably higher.

A carefully selected used module from a donor vehicle can potentially reduce that cost dramatically—but there are some important caveats:

1. Fix the reason the original module failed.

These Odysseys can develop water intrusion in this area. Installing another module without addressing the leak risks damaging the replacement too.

2. A used electronic module is always somewhat of a gamble.

A donor unit may have been exposed to moisture or other problems during its previous life, even if it looks fine externally.

3. Installation may involve more than simply plugging it in.

When replacement modules interact with vehicle security and immobilizer systems, key/immobilizer registration or programming may be required. That's where having the proper equipment and knowledge becomes important.

4. Where the donor vehicle lived can matter.

For this particular repair, I deliberately didn't source the replacement locally. It's coming from an automotive recycler in Rancho Cordova, California.

Why California?

The Sacramento area has a considerably drier climate than Maryland. That doesn't guarantee a perfect used module, but when I'm buying an electronic component that can be damaged by water intrusion, I'd rather stack the odds in my favor and source it from a dry-climate vehicle.

Sometimes repairing modern vehicles isn't simply about finding the right part. It's about understanding why the original failed, what the replacement requires, and how to make the smartest repair possible.
