Keyless entry question

Hi everybody. Just become an owner of 1997 550 silver on red.
I have two remotes, but non of them operate door locks, only
alarm/start disable system. Is that normal?
Please advise

GPW- What you describe are the symptoms of the remote batteries needing replacement. Ferrari actually recommends replacing the batteries every 6 months, which is kind of overkill, but I do replace mine annually with Duracell MN21 batteries. Any 23A/A23/MN21/21/23 alkaline 12 volt battery will fit, but the Duracells do not leak, so I use them. For a quick change, RadioShack will have a battery that will fit.

If you are actually able to open your car door with the key without the alarm going off, your alarm was never armed and all that was armed was the immobilizer, which automatically arms from 60-120 seconds after no input to the alarm system if the engine is not running.

My car had exactly the same symptoms when I first received her.

Thanks for the info.
The car came with 2 remotes and non of them open or lock doors. You right about immobilizer going off after 1-2 minutes, but if i just open any door alarm sound goes off too. I will try to replace battery in remote, but i don't think that is the case.

Very strange. Let us know how the battery change works. Here is a document I wrote on the fobs if it will help. Have never heard of remotes that would arm the alarm and not lock or unlock the doors.

If the batteries do no help, an ECU reset might do some good. Helps get rid of the spare electrons.

Wow, Taz, I have never replaced my remote batteries. That's after 4 1/2 years and 40,000 kms....lots of remote use. But I was getting slightly nervous about it, so will replace them next week.

Onno- I think Ferrari's 6 months is overkill and probably based on the car being used several times a day. I use one year and that also prevents the battery from leaking, although I have never seen a leaking Duracell. I even put a drop of battery terminal treatment on the contacts with a toothpick.
