transponder chip for key fob
 

does anyone program these? i need 1 for my spare key

Hi Kevin,

Just to clarify, is the problem you're trying to solve starting the engine or operating the remote central locking?

The transponder chip deals only with engine immobilisation.
The printed circuit board and buttons deal only with central locking.

Hi Simon

i've got a working Key with a transponder chip, but my second spare key needs one as it's missing completely

I would drop a PM to Big Russ - he is a key guru and should be able to help you.

I'm in much the same position so would be interested to know the outcome.

You”d need to either visit Russ or send the EWS unit from your car. Russ has specialised equipment to program the chip with the correct rolling codes in the EWS (car’s security system). There are cheapo alternatives (EBay mainly) that simply copy the code from an existing key but they will fall out of sync rendering them useless.

There are others who do keys, may be one nearer to you, I’m not on my laptop to check. Click on the link in my signature below and check the services the club traders offer.

I don't think there is anyone near you that offers it to be fair. I can do it but I'm Midlands based.

i'm willing to travel to Birmingham.. but leeds is alittle too far for me in 1 day, how much do your charge?

No worries! If you can't find anyone closer give me a shout. £40 for a transponder supplied and programmed.

would i need to buy the circuit board for it? my second key is completely empty

i take it i would need to travel up to u with the working key?

Ah ok so it’s a completely empty case with just a cut blade that you’ve got? I’m assuming the key doesn’t start the car? The PCB is for central locking the Transponder is for engine starting. I can provide an entire key, supplied cut and programmed for £90. I would need the car to do it.

yea the key is cut just need the circuit board and chip

Hi everyone,

Anyone know if a new transponder and circuit board for a LR Discovery 2 would work for a MG ZT. Physically they look the same although the circuitry seems a bit different.

Also, I need a microswitch for the circuit board.

Alternatively, does anyone know where I can get blank transponder chips and circuit boards? Also it needs to be 315MHZ.

Many thanks,

John

The landrover keys I have seen on ebay have ID73 transponders which are not suitable for Rover 75 or MG ZT. You need ID44 (PCF7930 or PCF7935). These must be programmed to your EWS. Therefore you must remove your EWS and send it for matching a transponder or have your car present and EWS removed in order to match a transponder.

I have a couple of PCF7930AS transponders, the original type that are present in the original keys, not Chinese clone transponders, these are £35 each and includes programming - you would need to send your EWS to me though.

I have two 315Mhz remote boards ( I also have a couple of 315Mhz receivers), I am selling the remotes for £30 each, which includes UK mainland postage.

These are 'new old stock' not refurbished, second hand or Chinese clones. Therefore you can be sure that they have the quality micro switches, as they are 100% original remotes.

PM me if interested in the above.
