Cayman G1 - cold sensitive??

[kipperonabike]

Cayman '58: Garaged for last 10 days, wouldn't respond to unlock - tried other key, same response. Opened fine manually, all entry lights came on. I nervously commenced ignition and it started fine. Then a couple of minutes later I switched PCM on - no graphics.....about 2 minutes later the graphics very slowly faded into focus.

It hasn't been particularly cold yet so I'm a little concerned about what might happen if I leave it garaged for a proper long spell. Surely a german manufactored car shouldn't be this cold sensitive?

I keep my Boxster connected to a CTEK charger if I'm not using it for any length of time

Assuming that Gen1 are similar to Gen2, the alarm system shuts down the remote controls after 7 days to conserve energy - hence manually opening the doors. However, if the battery were failing to that extent, you would not be able to start the car and once the engine is running the alternator should be pushing out 14.2V which should be enough for the PCM.

The car goes into power saving mode after 3-4 days. To reactivate the alarm system to use the remote a gentle tug on the drivers door handle is needed.

Excellent - that accounts for it.
And as a by product I have scoured the forum and learnt all about trackle charging and the horrendous price of new batteries!

This. Put the key in the drivers door, turn it counter clockwise then back and remove, it turns the 'listener' back on and the key will work again.

But, if you're having other power issues (which will be exaggerated as it gets colder), it can be a sign your battery is on the way out. Get a Bosch Silver in there and throw away the Porsche POS.

yup same for me, when i left the car on long stay, it wouldn't unlock remotely after 8 days. Opened manually and key in ignition sorts the "problem"..

no need to insert key.

just lift the door handle as that wakes the car .. you can then unlock as normal
