Can the Acura TSX FOB work for our RB1? I thought they work on a different frequency? I know the TSX can seems to be able to work for the CU2 Euros, but can't work on the CL9's due to freq difference.

If it is workable I would most prob like to get one too as the cheapo flip key mod off ebay is.... cheapo ?

do you know the frequency for our RB1? will get the key cut first then re-program the security chip with the car. last bit will see if the frequency is match, otherwise will swap the frequency chip too. i'll make this key works as it just feel too good

No idea what our frequency is. I went with the cheapo e-bay mod. I spent a total of $32. $22 for the casing plus shipping. $10 to cut the key, I have read that some have spent $40 to $50 cutting the key at specialist places.

But hope this thread helps, the CL9 and CM5 Accord boys are also attempted the mod with the TSX key

What I gather is that the all that is needed to enable you to start the car with the key is to get it cut and remove the immobiliser chip from out original remote to be put into the new remote (just like the ebay cheapo flip key mod)

Problem is the frequency of the lock and unclock. One of the guys even changed his control unit so that the frequency would be the same, but it didn't seem to work.

they have a different approach then I planned. am going to get the key cut 1st, then program the immobilizer using my own car. if it doesn't work, will swap the transponder on original key to the flip key. thats how the owners in China made them works on CRV, CM5 and RB1......fingers crossed :)

evo, u know which fourm i'm talking abt and check them out

ok, here is the update/verdict..........it doesn't work on RB1. swapped the frequency transmitter on original remote to the acura flip key. unable to re-program by my own.

it works on CRV at overseas which having the same frequency transmitter as ours in Australia. anyone knows any shops can help or any electronic engineers here can help

What is that chip you've marked?

It depends how they set the frequency. There are various ways to do this. One of the most common is a crystal. Not sure if this is how they do it in car remotes though.

The silver cased component to the left of the bit you highlighted looks like a crystal. Have a look at that to see if it has any numbers on it. They will usually have their frequency stamped on them.

I did a bit of a search on car remotes. You can get integrated RF and microcontroller chips. It would probably use something like this. The crystal I mentioned is used to set the frequency that the microcontroller runs at. This would likely be higher than the transmitter frequency.

The microcontroller would then divide this frequency and send it to the RF oscillator which is the frequency that the transmitter would work at.

So there are two ways they could use to change the transmitter frequency that I can think of (if they are using a configuration like this). First is to program the microcontroller for all the remotes the same and use different crystals. This would mean that all of the frequencies inside the micro are changed and so would the transmitter frequency. In this case if you swapped the crystal it may work.

The other option, and probably the most likely is they have simply programmed the micro differently to divide the frequency differently. In this case, if they have used the same micro in both and they have the same pin outs you should be able to swap the micro and it will work.

This is based on alot of assumptions. Like the chip used has internal flash memory of some sort. If you can post up some part numbers from the major chips that could be a clue. Hope this helps.

The part with the red bit around it? That doesn't look like a crystal. They will usually have a metal casing around them for shielding because they are very sensitive to temperature and emf interferance.

If you want any more help I'll need part numbers off the chips.

Another possibility is that you damaged the crystal while removing it.

will give it a try to re-program it again tonite and will advise the part nr too

would love to know the results, as i have purchased the 09 TSX key from america, finding out that the feq is completely different for my australian 09 CL9.

acura key: metal bit has "500",
chips "OMRON 060303 743E", "5101 03 60810", "13.560 RVR615"
original: metal bit has "5000",

i am confused ausaccord..

so what your saying is that, we just have to change the chips around? and it will definitely work on my CL9?

Forgot to reply. I had a look for any of those parts. Was hoping if I found some datasheets I could find out some more info. Would have to have a look before being able to do anything more.

From the looks of those parts you said you swapped they do look like frequencies in the part number. If they were the same pinout and it still didn't work then there may be another microcontroller dividing the frequency again in software but thats a guess.

i did not say it definitely work on CL9 but thats how the chinese modified to work with RB1, CM5 and CRV in China. in addition, i proved that it did not work on my RB1 in Australia at this stage.

its upto you if you want to give it a try. only cost me 10 bucks for a mobile phone technician swapping that chip between Acura and original remote.

thats the idea for swapping that chip unless the technician burnt that chip when swapping. i'm hold on doing nothing at the moment until i can talk to a honda technician (if possible)
