My 2004 Camry Standard came with power locks but no remote locking. Toyota say the parts are $137 and the fitting about $300. The fitting costs seem very high. All four doors are locked simultaneously by the switch on the drivers door and so it would seem to be simple to install the ECU in the same circuit. Since all other Camry versions come with remote locking, presumably the cable loom is already there.
Can anyone advise?
