I followed the directions according to vqpower.com and it works great. I used a different buzzer (actually a siren). Here's a video clip of it. I'll post up the part number from radio shack when I get home.

Good stuff

 

what's the part #?

 

i gotta do that mod....

 

Is there anyway you can post link to that thread?
And part number please.
Sounds COOL!

 

LOL... I did this MOD aswell, my car sounds like a chirping bird when I lock it. Where did you get the siren from???

 

i need to get my lazy *** around to doing it

 

How did you guys do it? Details please???!!!

 

vqpower.com

 

sounds cool at first, but you know within 2 weeks it's going to be annoying as hell..............

 

I agree with fearthegecko. The reason I did not choose that particular buzzer for my mod is for the same reason. It starts to become quite annoying. Keep that in mind.
Anyway, for those interested in this mod, I believe that the VQPOWER website makes the mod more difficult than it is. There is no need to add an additional relay. If you have questions on how to do this without the additional relay, PM me. I did a write-up on this several months ago. Search for it, you'll get all the info you need. My advice: stick with a conservative but cool-sounding piezo buzzer.

 

i want mine ot beep like bmw's?

 

are those white turn signals?

 

im in the same boat. about a week after i did this mod i was so sick of the chirping sound. everyone makes fun of me when i lock my car. anyone know of a better sounding buzzer?

 

Maybe someone who has access to Toyota/Lexus part info can provide a part number for the buzzer that Toyota/Lexus uses for a buzzer.

 

Hmm your probably right, I could see it getting annoying. It hasn't so far but I'm pleased. The part number is 2730079.

I was thinking about that and your right you don't need a relay. Just splice red on buzzer to 12v and black to the BCM gnd output. Sigh....

 

You could (I am sure) easily walk into the BMW or LEXUS dealership and ask for the buzzer. I think I am going to try to do that this weekend.

Anyway, to do this mod without the relay, read the following:


I was interested in the "Alarm Beep" mod, you know; the one that makes your car beep when you lock all the doors w/ remote and arm the alarm. Lights flash, alarm is armed—but I too wanted to hear when it was being armed, not just make sure to watch for the flash. There was a link posted that takes you to VQpower or something like that...I went to the only link I knew of for that mod, and it mentioned the need for a relay, showing the schematic and all...

Well, I did some testing and found out that the mod was cheaper than what that article said. I did find the article helpful, but there is no need to buy an extra relay. For those who already knew this, skip to the last few paragraphs. For all others, learn from my experience and save time and money.

I went out and purchased the relay and piezo buzzer that were pictured in the diagrams. I bought several buzzers to find what I liked best. I followed the instructions for locating the relay in the trunk. As I got to looking at what the article said about the need for another relay, I realized the mistake in the logic:

Relays are generally used when you want a smaller power source to drive a larger one. Well, in the case of this mod, the location and wiring of the additional relay is completely unnecessary. Why? Because the author of the article used the exact same wire for the relay coil as he did for the relay switch. What am I saying? That the extra relay does not add any benefit.
Using the same wiring for both energizing the coil AND providing a power source for the relay's switch is an unnecessary use of a relay.

If you test the orange wire, you see that it is not a constant ground. The ground is only completed when you press the "lock" button. This ground (or sink) comes from the BCM (don't worry, just take my word for it) and is only constant for the duration of the flash from your lights (signalling alarm activation).

In essence, by using the green/orange wire for power (connecting it to the red wire on your piezo buzzer), and the orange wire (connects to the black on your piezo buzzer) for ground, you need no relay. I just bare a little bit of each wire, wrap the extra wire that will go to the buzzer around it, solder, tape it up, then DONE. Effective placement of the buzzer is necessary for optimal sound. Inside the trunk, the piezo is quieted significantly by being sealed from the outside. The solution? Relocate the buzzer (preferrably to a protected spot outside of the vehicle). You will notice that in the trunk, there is a black wire that goes into a weather seal, just below the relay that has been described above. I just cut a small hole in that seal, ran the wire and buzzer to the underside of the bumper. I also added another buzzer (better ability to hear alarm arm) to the FRONT of the car by accessing the same-colored wires (green/o and o) that are in the wire bundle on the driver's side, beneath the kickplate. If details are needed, let me know. Anyway, just trying to save you some time and money.

 

Nice work. Anyone have any other clips of differnt sounds we can add?

 

the toyota beep would be bad a**. my moms avalon has it and its sounds sweet. im going to look into finding one from the dealer!

 

I think the Toyota/Lexus and BMW "beep" "beep" buzzer is very nice. It has that sophisticated feel to it. My old 3rd gen used to beep once when I locked the doors from the keypad. There were two buzzers in each front door and they beeped very similar to the Toyota/Lexus, only once though. I took one buzzer out once because it stopped working. Nissan also used a very similar system on the last generation Pathfinder (and possibly other models) where the factory alarm beeped when armed. It was just as loud or louder than the Toyota/Lexus beep.

 

im asking my friend that works at BMW if he can get it for me ...
