Guys pleaaaaseeee help meeeee

[AbuS3ood]

guys i have bought 10 keys from ebay, i always buy from ebay and works well,
the keys are for camry hybrid with keyless, part no HYQ14AAB, ALL keys are work when pressing the buttons, but 4 of them when i program the vehicle dont detect when i stick it to the start button but the other 6 detected immediately and programmed, i have replace the batteries and no joy, i always do reset using the chinese dongle and i have techstream, please help me how to fix them.

each key is bought from different seller, are AVALON and camry hybrid fobs are the same?

You need to make sure that the emblem on the back is the same (silver or not silver). The Avalon and Camry fobs are NOT interchangeable.

Secondly, some of these cars will not accept a used fob, if it's used it may not work.

they are all silver , are you sure that AVALON and CAMRY HYBRID keys dont work on each others? because the are the same remote with the same part no and fcc id HYQ14AAB

since i always do reset the car will accept the used proxy, any ideas are welcome

From all info I have, the two prox's are different parts across the board for every year they've been around.

I really can't speak for the Avalon prox (not as common here), but with authority on the Camry.....even with a reset, I have been unsuccessful programming used prox's.

i have noticed all sellers list the same smart key remote for camry hybrid and avalon even the big websites that sells remotes i say maybe the remotes wont work is taken from avalon, i only work on camry hybrid and we dont have avalon, i checked the keys from inside they almost the same some chips serial is different, it seems we both have the same problem,

do you think resetting using TechStream will give different result than resetting using the dongle? i'll do a try soon.

If it doesn't work with techstream, then it won't work with the dongle.

The dongle is very hit and miss. It very well may program the chip---which is the same across the board, just 4d67, but the prox functions may not work.

Non prox= no problem programming keys.
Prox= good luck, it may or may not work for prox function, and from my experience and folks that I know's, it's not shooting fish in a barrell w/ the orange tool.

im used to do it using the dongle and will try techstream,
the problem is not matter of programming, in the moment some keys are detected immediately and others the car don't see ,

the prius smart key programming is harder than camry, but i can do it easily via techstream and never had problems with any keys,

Ah yes, the Prius. Don't plug that orange dongle into it, or you will probably be sorry.
Techstream is your best bet on that car particularly.

Did you actually test the voltage of your batteries with a multi-meter? Just a stab, but I've found fresh batteries out of a package to be too weak to program Nissan prox, for instance....perhaps your issue?

These cars are extremely finicky when it comes to what they want to see in the prox. I always buy new ones, have good equipment, and still have programming issues with Toy prox at times.

I bought a used lexus fob from ebay cheap. Red LED would show normal working condition but whatever I tried, it would never program to anything. A friend had a module to read frequencies off a remote. The Lexus fob shot off a weak and off frequency not matching OEM. In short the remote was hurt after being dropped or catching some water... Useless and I was out a couple bucks.

The first thing i did is testing the voltage, original installed battery shows 2.9 v and i installed a brand new battery with 3.0+v but same results :(, after testing the remote freq and found working i think the problem with the prox IC which is shown in the photo below
HYQ14AAB (http://farm4.static.flickr.com/3475/3858493375_31638ffa99.jpg)

i must keep searching until i find the reason and fix it because they are massive loss for me, the 4 refuse to program worth more than 800$ :S

Its matter of luck, i bought more than 25 remotes from ebay, for lexus and prius and camry, they all worked except these 4 camry hybrid fobs, the freq is good on test, the proxy is the problem

any help or suggestions or opinions are welcome.

Again, some of these cars, and don't ask me the logic, do not like used fobs. They smell the difference somehow.

you are right, there is no logic when dealing with toyota.

[AbuS3ood]

today a received 9 fobs that i ordered before i found the problem, only two of them worked, after opening all remotes i fount the remotes working have big Chip with WHITE writing ending with A, and the non working has the same chip but with black writing, the correct chip shown in the pic below
Correct IC (http://farm4.static.flickr.com/3475/3858493375_31638ffa99.jpg)

god only know how bad do i feel.
i lost 11 fobs because of the god damn toyota they shouldnt have the same Part no and FCC ID

another update, i called one of the of the customers who bought keys from me,he opened the remote and found the text on the black Chip was black and numbers similar to the remotes that wont work :-S

So the black chip is an issue? But if your customer as a black chip fully programmed then that might not be the issue.

I don't have schematics for these remotes but I'm pretty sure it's just a Tx system, not a TxRx system. Meaning it doesn't receive anything from the car, just transmit.

The only other thing I can think of is rolling codes. Have you tried wiping out the remotes from the car and programming over?

thanks for ur interest, i dont understand what is Tx and Rx but the car send and receive data from remote, because when u try to start the car it search for the remote and send signal if the remote replied it start, otherwise dont.

i always do reset( clearing all the keys) and some remotes are immediately programmed but many wont, all the remotes are used.

i tried TechStream but the same result.

good finding friend,i use techstream to do prius never had problem,buy once i program 09 corolla with smat key,has same part no. as you have,refused to accept keys.then car secuirty system locked up after few tries.i asked the custmer to take it to dealer,but custmer just change the fob battery and call anter guy with small denso toyota scan tool ,and he did it without resetting the smart key system and car accept the key.
i know camery,corolla ,avalion use same key fobs part no.

the first thing i did is to replace the battery although the old one was 2.9v , still no solution,

any one can confirm that the avalon and camry hybrid smart keys are the same and work on each others?

Tx= transmit
Rx= Receive

I still think it's a transmit remote only. 95% of remotes are transmit only. I found nothing on the net that those remotes save any info like the BMWs and Benzs

Could be the programmer you are using. But one last thing to try if it's a rolling code issue is to short out the battery pins on the remote while battery is out for some seconds and try again. I'm really lost on this one.

the programmer is working well, and the problem in the keys, can you please explain more details about shorting the pins, i hope it works, thanks for ur help

[Cozz]

Simply take out the battery and jump the positive terminal to the negative terminal of the board of the battery leads. for a couple of seconds. Maybe discharging any caps or what not on the remote to fully reset it by doing that.

[AbuS3ood]

i did it but no joy :-(

[AbuS3ood]

whats up guys? no updates no ideas?

[hauwkee]

any update maybe u can read the chip in working keys and in non working keys to check if it s same consistency
