keyless and tpms
hey all.. 06 T and C with 102000.. i have replaced 2 tire sensors over last year and now tire light is on again... but this time it was preceded by the keyless not working for one day...( both key fobs)... how is the keyless and TPMS connected and what do you think...by the way... had rear bumper and liftgate replaced year ago after rear ended... is there a connection there ? i remember the keyless not working for a few days after i picked up van at the body shop....thanks alot

SENTRY KEY REMOTE ENTRY
MODULE
DESCRIPTION
The Sentry Key Remote Entry Module (SKREEM)
performs the functions of the Sentry Key Immobilizer
Module (SKIM), Remote Keyless Entry (RKE) Module,
and the Tire Pressure Monitoring (TPM) System
(previously part of the Electronic Vehicle Information
Center (EVIC).
The SKREEM is located in the same location as
the SKIM was and is mounted the same way. It looks
identical, but has added capabilities
and
OPERATION
The battery operated tire pressure sensors lay dormant
(Park Mode), then wake and start transmitting
(Drive Mode) when the vehicle first reaches speeds
over 20 mph (32 km/h). Once the wheels stop rotating
for a period of approximately 30 minutes, the
sensors shut down until again awaken. Although not
transmitting as when in Drive Mode, while in Park
Mode, the sensors still transmit approximately once
every 13 hours to let the receiver know air pressure
status at that time.
Each sensor transmits tire pressure data approximately
once every minute. Each sensor’s (transmitter)
broadcast is uniquely coded so that the wireless
control module (WCM) can monitor the state of each
of the sensors on the four rotating road wheels. The
WCM (located in the SKREEM) automatically learns
and stores the sensor’s ID while driving after a sensor
has been replaced. There is no retraining necessary.
The receiver only receives information from the
four rotating tires. A fifth sensor may be located in
the spare tire wheel, depending on vehicle options.
Although this fifth sensor may be present, it does not
broadcast any information because it does not rotate.
I would suggest that you start with it's antenna condition as its seems both TPMS and keyfob are having problems

well.. i'll keep you guys informed just in case anyone else has this happen but for now..... right front tire sensor showed dead so i had it replaced at local shop on wednesday.... so far so good... light is off and keyless working fine again... tech said unsure of the connection between the two at this time but for sure we know the right front sensor is bad so that had to be done first... he says both the keyless and the tire sensors transmit to the same WCM but on different frequencies so ???? knock on wood...

just a follow up since i sure someone else will oneday experience this.. now 6 weeks or so after tire sensor was changed out and all good... no tpms light and keyless is working fine ... not sure the connection but obviously there is...
