i tried very hard but i was not able to find the datasheet
but model is- xy-mk-5v
but model is- xy-mk-5v
Googled: xy-mk-5v 433mhz
Got lots of hits. The first several were related to an Arduino forum. Here is the first one: http://forum.arduino.cc/index.php?topic=129749.0
Apparently, it is just CW at 433 MHz and does not have any coding ability built in, so you will get lots of interference. One of the other links also sells the HT12E and HT12D to give coding and reduce interference (http://www.ventor.co.in/index.php?main_page=product_info&products_id=261).
Without an antenna, range will be extremely limited and without some method to code, you will have just one, on/off (when you are lucky) function. By itself, it is probably not suitable for an RC car.

i am sorry sir that i was not able to give you details about it
@jpanhalt
sir i have the encoder(ht12e) and decoder(ht12d) but i was not able to get tx rx working.
I have also made a pic microcontroller board using PIC16f873.
can i use the tx and rx with microcontroller

Yes, a microcontroller can be used with the TX and RX that you have. That is basically all that the HT12 chips are. Google on software UART.
However, if you can't get the receiver and transmitter working at all, then adding an additional layer of complexity isn't going to help. Have you checked any of the links to be sure you wired the modules correctly?

yes i have checked many links but all in vain
could it be possible that my tx rx are damaged . if so then how can i check that they are working.

i bought the encoder decoder board from following seller
http://www.ebay.in/itm/RF-encoder-d..._203&hash=item41731b7895&_uhb=1#ht_1227wt_952
the decoder board have an led connected to vt pin of ht12d which blinks when the tx is also connected to supply and do not blink other wise.
so i now think that the tx rx pair must be alright.
but when i connect 4 leds to data pins of decoder board they are always on.
and do not turn off even when the four switches connected to the encoder board are pressed.
