2001 BMW Z3 3.0i - Programming 2 button security system remote help

First time posting here. Great site. I've learned a ton from all of you. I recently purchased a 2001 BMW Z3 3.0i with 89,000 miles from my Mom who really didn't keep up with it very well. But I am not complaining because it runs great and I was able to get it from her for a great price. I've spent the last week just simply getting it cleaned up and looking nice again.

Anyway, one of the things on my "to do" list is to get the 2 button remote working (separate from the key). When the buttons are pressed the remote's little LED does light but nothing seems to happen in the car.

The LED on the dash above the stock stereo flashes once every few seconds or so (haven't timed it to be exact).

I followed the instructions from the security system book to the letter (starting by closing all doors, trunk, and hood, opening and sitting in the seat and closing the door, cycling the ignition to the 2nd position 5 times, etc.) and it isn't working.

So a couple of questions:

1. In step 2 of the instructions it says:

The security system must be in "disarm" mode. The key must be removed from the ignition key slot.

I get that the key must be removed from the ignition. But how do I know the system is in "disarm" mode.

2. In step 6 it says (after cycling the ignition switch 5 times):

The red status LED will illuminate continuously, and the siren will "chirp" once, to indicate that the code-learning mode has been initiated.

I get the single "chirp" but the red status LED on the dash does not illuminate continously. It just keeps its every few second single flash and never changes.

I go through the rest of the steps and I get the 2 "chirp" confirmation at the end after closing the driver's door at the very end but the LED still keeps its every few second single flash going like nothing ever happened and the remote still doesn't lock or unlock or arm or anything.

I think the fact that my LED isn't illuminating continously in step 6 is probably the reason it isn't work but didn't know why it isn't doing what the instructions say.

Anything that I can check?

Thanks very much.

"The LED on the dash above the stock stereo"

You lost me there, what LED above the radio?

Sorry, the car is still kind of new to me and I am at work right now so I am going by memory. In the center console there is a red security light/LED between the stereo and the upper AC vent on the passenger side. It normally flashes once like every 3 to 5 seconds or so, and the instructions for programming the remote in the BMW security system manual specifically mention the LED in step 6:

"The red status LED will illuminate continuously, and the siren will "chirp" once, to indicate that the code-learning mode has been initiated"

My problem (I think) is that the red status LED doesn't illuminate continously. It just keeps flashing at its usual pace every 3 to 5 seconds. Maybe there is a different one I should be looking for?

Thanks.

Does your FOB looks like this? and the LED with the glass breaking sensor looks like.

Use these instructions. You should have the Key with the 3 buttons on the key head one to lock one to unlock and one for the interior light. If you have the key and a remote fob you have a pre 2001 bmw system or an after market system.
This is for BMW Z3 2001 - 2002.
I used this last week to program a new key on our 2001 Z3 3.0I

Procedure:

1. Enter the vehicle through the driver's door with all of the remote keys to be programmed. Close the driver's door.

2. Insert the first key to be programmed into the ignition and turn to the "On" position (not the "Start" position), then switch off within 5 seconds and remove the first key.

3. Within 30 seconds of turning the key off, press and hold the "Arrow" button.

4. While holding the "Arrow" button, press and release ("tap") the "BMW Logo" button three times within 10 seconds.

5. Release both buttons. If the initialization for that key was successful, the doors will immediately lock and unlock.

6. If additional keys need to be initialized repeat steps 3 through 5 with the remaining keys within 30 seconds. Do not re-insert subsequent keys into the ignition.

7. Switching the ignition to the "On" position completes the initialization process.

If programming is unsuccessful, repeat this process. Further diagnosis may be required if the initialization is still unsuccessful.

Yes, my FOB does look like the pic. I'll have to confirm exactly what the LED looks like later this evening. Thanks.

I don't have a key with the 3 buttons on it, unfortunately. I only have a BMW key with a single button in the middle that illuminates the blade of the key. No other buttons are on it. I have the separate remote key fob shown in the post above.

Thanks very much for the input. I think I'm following the instructions from the manual precisely but something must not be working right in the system since I can't get the LED to stay continuously lit like the instructions point out. I do get the "chirps" where expected though during the programming attempt.

The stock location for the alarm LED is found either with the other switches in the center console, i.e. AC/REC button but sometimes is found in the rear of the console between the seats. If you can, take a picture of the LED location. Are you able to lock the car using the key? do all the doors lock? other words, is the central locking system working properly? When you try to arm/lock the car you get nothing? no chirps at all? or are you getting 3 chirps?

With the key itself, I can lock the car no problem. It automatically locks the passenger door and gas door as well.

When I use the 2 button remote control however, nothing happens. No lock/unlock, no chirps, nothing. The light on the fob is working so I assume it is putting out a signal but I haven't verified that.

The part that got me on the instructions was that the status LED was not turning solid red. It just keeps flashing about once every 3 to 5 seconds or so. Later this evening I'll see if I can post a pic of where my status LED is (or what I think is my status LED) :-)

Thanks very much.

Sure you're not mistaken the status led with the led on the radio? the radio also has a led on the upper right hand corner that flashes when the car/ignition is off.

Wow, I feel like an idiot! Told you I was going by memory. So yes, I was mistaken. It is the little light on the radio itself that I was looking at.

I see now that there is an LED light back by where the buttons are to raise and lower the top but there is no light whatsoever at any time. So I guess maybe that's the problem! Is there a fuse somewhere for the system that I could check to see why it isn't working, or is there a switch somewhere that controls that?

Thanks so much for the guidance.

Check the fuse box, legend is under the lid. The LED light is merely a status indicator, should have no effect on the operation of the alarm, something else is going on.
Have you change the battery on the remote? How old is the car battery?

Not sure how old the car battery is, but I don't suspect it has a problem. All fuses checked out, and the fact that the system does make the "chirps" as expected while programming the remote must mean that it has power anyway. It just doesn't learn the transmitter code.

I'll make sure it has a fresh battery and try again later tonight.

Thanks.

Ok, so I replaced the battery in the remote transmitter, ran through the programming steps again, making sure to pay attention to the real security system status LED back by the convertible top up/down buttons, and am happy to report that everything is working now. I did notice that the status LED took a couple of seconds to go solid red after step 6, but once it did I pushed the big button on my remote for a few seconds and then completed the remaining steps. All is working now.

Thanks very much for the assist.
